opo··on Meta claims torrenting pirated books isn't illegal without proof of seeding
As a general defense, the research exemption is only applicable where you can reasonably claim you are using a patented invention for research purposes. But if it looks like the reason you are infringing on the patent is that you want to use the patent, but don't want to pay for the rights, that is not going to work. Even if your intentions are not commercial, making or using a patented invention is still infringement. Like I said before, it is highly unlikely that someone would know about the infringement if it was just done for personal use, but that doesn't mean it isn't infringement.

>...There were plenty of anti-federalists around during this time. They got to air their complaints and opinions. Nobody listened to them because the articles of confederation, and the loose, weak federal government it built was just that useless and broken.

Nobody listened to them? I think most historians would agree that they were instrumental in getting the bill of rights added to the constitution. For example:

>...Anti-Federalists in Massachusetts, Virginia and New York, three crucial states, made ratification of the Constitution contingent on a Bill of Rights. In Massachusetts, arguments between the Federalists and Anti-Federalists erupted in a physical brawl between Elbridge Gerry and Francis Dana. Sensing that Anti-Federalist sentiment would sink ratification efforts, James Madison reluctantly agreed to draft a list of rights that the new federal government could not encroach.

I don't think that is correct. The patent act states:

opo··on DA, sheriff, who shared woman's nude photos on phone are covered by QI

The modern over-expansion of QI actually started in 1982:

>The modern test for qualified immunity was established in Harlow v. Fitzgerald (1982).

Since then, while several justices (Kennedy, Scalia, Thomas, Sotomayor ) have sometimes dissented and criticized the over expansion of QI, the overall court doesn't seem to want to touch it.

>"Socialism never took root in America because the poor see themselves not as an exploited proletariat, but as temporarily embarrassed millionaires."

That quote is from Ronald Wright. It appears to be a paraphrase from this Steinbeck quote. In the actual quote you can see Steinbeck is not trying to criticize the poor, but rather champagne socialists:

>...Except for the field organizers of strikes, who were pretty tough monkeys and devoted, most of the so-called Communists I met were middle-class, middle-aged people playing a game of dreams. I remember a woman in easy circumstances saying to another even more affluent: 'After the revolution even we will have more, won't we, dear?' Then there was another lover of proletarians who used to raise hell with Sunday picknickers on her property. I guess the trouble was that we didn't have any self-admitted proletarians. Everyone was a temporarily embarrassed capitalist. Maybe the Communists so closely questioned by the investigation committees were a danger to America, but the ones I knew — at least they claimed to be Communists — couldn't have disrupted a Sunday-school picnic. Besides they were too busy fighting among themselves.

opo··on America desperately needs more air traffic controllers
A big problem with US air traffic control is that you have the regulator regulating themselves. The USA is one of the few countries where the regulator also provides the ATC service. In comparison to Canada, the US government run air traffic control is noticeably less productive and more expensive.

The first proposal to break out the regulation of air traffic control with the provision of the air traffic control was done by the Clinton administration. Support since then has been bipartisan and opposition has also been from members of both parties for various reasons. (I read somewhere that one of the biggest long time opponents of breaking out the air traffic control has been the associations of owners of private jets as they currently pay about 1% of the cost of ATC, but are closer to 10% of the flights in major airports. In reality, owners of private jets can likely afford to pay a more proportional percentage of the costs they impose on the system.)

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.”

opo··on When a winter storm trapped a luxury passenger train near Donner Pass
Lol. It is pretty clear that the key point of the summary I quoted was that the consensus among economists who have studied this was that at least 60% of the decline in airfare prices can be attributed to deregulation. You didn’t need to put in all this effort to misinterpret it. (No one was adding percentages or whatever you were claiming.) Them rounding to the nearest multiple of 10 is reasonable - not rounding would be implying a higher precision than is really warranted.

If anyone is reading this thread, it illustrates a problem common in on-line discussions. Someone will make a big claim that contradicts the consensus of the experts in the fields who have studied the issue. (I have found that when discussions touch upon economics, it is virtually guaranteed, but it happens in many areas.)

Someone then points out that if the person is correct and the consensus position of the experts who have studied this issue are all wrong, the burden of proof is on them. The original poster won’t try and do this but will instead try to come up with a reason that those who devote their careers to actually studying these issues can’t be trusted or are incompetent, etc. Unfortunately, at this stage, the person is usually even more entrenched in their personal pet theory. They usually aren’t so blatant as to say “Either they are utterly incompetent or lying.”, but that is where we are.

opo··on When a winter storm trapped a luxury passenger train near Donner Pass
33 * .6 = 19.8

My general feeling is always that if someone is going against the consensus of the experts who have studied something (whatever the issue is - it could be climate change or GMO food or effects of airline deregulation or whatever) I think the burden of proof is on the person who claims the experts are all wrong.

opo··on When a winter storm trapped a luxury passenger train near Donner Pass
The general consensus among economists is that deregulation had a big effect on airline prices. For example:

>...Every serious study of airline deregulation in the intervening years has found that travelers have indeed benefited enormously. As we documented in our 1995 Brookings book, The Evolution of the Airline Industry, airfares, adjusted for inflation, fell 33 percent between 1976—just before the CAB instigated regulatory reforms—and 1993. Deregulation was directly responsible for at least 60 percent of the decline—responsible, that is, for a 20 percent drop in fares. And travelers have benefited not only from low fares, but from better service, particularly increased flight frequency.

Having one buyer or seller of a product or service is neither called "price gouging" or "price fixing".

There is really no evidence of that. (The basic concept of rent seeking is covered in any econ101 micro textbook.)

As the wikipedia article points out, this is really a textbook case of rent seeking. This is not what I would consider a controversial opinion.

>...However, I think the fact is that the manufacturers who set it up like this don't want to deal with customers, and they establish dealerships that agree to a certain quality of service that the manufacturer wants associated with their name.

No, this was not what the manufacturers wanted. States set up franchise laws to prevent car makers from directly selling their cars and they generally are not viewed as benefiting the producer or consumer:

>...Economists have characterized these regulations as a form of rent-seeking that extracts rents from manufacturers of cars, increases costs for consumers, and limits entry of new car dealerships while raising profits for incumbent car dealers.[2] Research shows that as a result of these laws, retail prices for cars are higher than they otherwise would be.[2] [3]

opo··on In Colorado, a marriage of solar energy and farming
When utilities are required to do net metering (i.e. buy power whenever it is produced at essentially the retail rate rather than buy what they need at the wholesale rate) it is a huge unsustainable subsidy to wealthier homeowners paid for by the less wealthy. It's free riding on the reliability provided by the grid, putting large costs on the less well off. As these costs grew, that has also provided an incentive for consumer solar installations to increase.

As the statista.com report says >...Rooftop solar photovoltaic installations on residential buildings and nuclear power have the highest unsubsidized levelized costs of energy generation in the United States. If not for federal and state subsidies, rooftop solar PV would come with a price tag between 117 and 282 U.S. dollars per megawatt hour.

https://www.statista.com/statistics/493797/estimated-leveliz...

Looks like that report is a year old, but I doubt the installation costs have really gone down much since then. (Panel prices come down, but labor costs, etc don't.)

Providing the infrastructure and reliability of the grid is very expensive, so there is a huge difference between the wholesale costs and retail rates for delivered electricity. Money is limited and is fungible - a dollar spent subsidizing utility solar will go much, much further than a dollar spent subsidizing rooftop residential solar.

opo··on Satellite powered estimation of global solar potential
>...Haven't we more or less concluded that a million piecemeal rooftop installations of solar are about the worst way to do it?

The data shows that you are correct. Utility grid solar provides low cost power and consumer rooftop solar does not and will not. The rooftop solar price is usually hidden because no power source has been as subsidized as rooftop solar. Besides direct subsidies, wealthier home owners have often been paid the retail rate for the electricity they sell to the grid which causes higher electricity bills for those who can't afford to put panels on their roof - sort of a reverse Robinhood scheme.

As the statista.com report says:

>...Rooftop solar photovoltaic installations on residential buildings and nuclear power have the highest unsubsidized levelized costs of energy generation in the United States. If not for federal and state subsidies, rooftop solar PV would come with a price tag between 117 and 282 U.S. dollars per megawatt hour.

>We don’t need to adjust for inflation since we are comparing nominal returns across the board.

Well there are things like TIPS, so comparing real returns across the board might be more helpful. Some of the returns from S&P investing will be in the form of dividends, so ideally the amount of taxable gains would also be included to get a better comparison.

I agree that even with the history of long slumps that stocks are still one of the best investments out there.

>If multiple SP500 companies are at risk, then I am going to bet Congress is going to shift into high gear to find a solution.

I think we might be in agreement that bailouts come down to systemic risk and political pull. Silicon Valley bank fails and people got all their money bank even if the accounts were far above the FDIC limits. Other banks fail at about the same time and account holders get only up to the FDIC limit. Maybe there was systemic risk there, but it feels like political pull was at least involved.

When the dot com bubble burst, many large companies failed but there was no concentrated action by Congress or the Fed to bail them out. Hence the lost decade for S&P 500 investors.

>At its worst, 1999 to 2009, SP500 total annual return was only -0.2%, per dqdyj.

The general claim is that Japanese economy has stagnated with low growth for decades and I don't think that has been proven false. For example, in the last year or two, the Japanese stock market has finally reached the values it had in the late 1980s. I am sure some Japanese economic indicators have done ok, but for example, one indicator of how well people are generally doing is to compare the GDP per capita over a period of time. In Japan, the GDP Per Capita in 1960 was about $500. In 1990 the GDP Per Capita was about $25,800 and in 2023 it was about $33,900. (In comparison, the USA GDP Per Capita in 1990 was about $23,900 and in 2023, it was about $81,700.)

Saying that Krugman was vindicated is quite a stretch. As the economist Noah Smith wrote:

>...In 2021, Krugman tweeted: "I like it and plan to steal it. This report does look like what you'd expect if recent inflation was about transitory disruptions, not stagflation redux".

As Smith pointed out:

>...But in late 2021, inflation spread to become very broad-based. Services inflation was always significant, and took over from goods inflation as the main contributor in 2022.

>The notion that this was just some transient supply-chain disruptions that was only affecting specific products was absolutely central to Team Transitory’s claims in the summer of 2021. And that was incorrect.

>...Team Transitory also called the end of the inflation at least a year and a half too soon.

>...So they didn’t entirely whiff here. They just greatly overstated their case. And their complacency in 2021 probably fed into the Fed’s decision to delay the start of rate hikes until 2022, which in retrospect looks like a serious mistake.

What did get vindicated was mainstream economics as taught in our textbooks. As Smith wrote:

>...Mainstream macro’s first victory was in predicting that the inflation would happen in the first place. In February 2021, Olivier Blanchard used a very simple “output gap” model to predict that Biden’s Covid relief bill would raise demand by enough to show up in the inflation numbers. His prediction came true. He didn’t get everything right — he thought wages would rise more than consumer prices, and he neglected the lagged effects of Trump’s Covid relief packages and Fed lending programs. But his standard simple mainstream model got the basic prediction right when most people made the opposite prediction, and this deserves recognition.

opo··on Who died and left the US $7B?
>...but it's common practice.

There are many web pages claiming this, but I haven't seen actual statistics on this loophole. To be clear, many, many, people borrow against the value of an asset - from the middle class up to the ultra wealthy and they can defer capital gains in that way. The claim with buy, borrow, die is that you can borrow for decades and not have to pay back the loan until death. Some claim that the rich just keep rolling over loans on to new loans to avoid paying interest/principal for decades. The reddit posting discussing this has been edited since it was first discussed on hacker news, but now it emphasizes that the bank and the ultra wealthy person come to some sort of agreement to share in the gains of the asset upon death. Considering the length of the agreement it seems it would difficult to come up with an agreement that would be fair to both sides in that agreement.

I saw that on reddit, /u/Taxing responded to a different post by the author of the reddit posting and was skeptical of how common this approach is:

>...I too went to law school, earned my LL.M. from NYU and have been practicing in this area for decades with broad family office clients ranging from a few hundred million to many billions, and yes have clients with public companies, private companies, and taken companies between the two structures. I’ve worked at every level and now sit on the boards, manage the relationships, etc., which I enjoy more.

>...I struggle to think of a single family office interested in a lifelong arrangement with Goldman or other firm at that level, providing them strings of participation and control. Over time, circumstances change, and they are not your friend.

So, maybe, the "Buy, Borrow, Die" approach is common practice, but I have yet to see any actual stats on it.
