> The amount of money spent is not limited to legal campaign contributions. There are also PACs, media spending (submarines, astroturfing, etc.), and other ways that money can influence public opinion on some issue. You can't really quantify this, but I'd be surprised to find anyone who would disagree that wealth itself will buy political power on its own without money ever changing hands. Here is a good example of what I'm talking about:
I'm aware of that. This is a thorough explanation of my view:

> QE benefits people with access to capital by propping asset prices. The people with access to capital are wealthy. Who benefits when real estate goes up -- renters or homeowners? Who benefits when the stock market goes up -- people with a wealth manager or people living paycheck-to-paycheck?
QE does, sort of, inflate asset prices. It also lowers interest rates, which makes it cheaper for people to buy homes. QE does a lot of things, and summarizing it as "inflates asset prices" is too simplistic. QE is usually undertaken, in part, so that people living paycheck to paycheck can continue to receive that paycheck, rather than being fired.
> Power is concentrated among wealthy people. This is true in general, but specifically I'm talking about a very small number of people who have a huge say in media, politics, etc. It is not scrutinized; the media ensures that. Yes, I think anyone with Koch-degree wealth has a huge amount of unaccountable power. There will always be inequality, but there are degrees of difference. At $5,000,000 of wealth, you might be able to get the mayor on the phone (that's a very generous upper cap on lifetime earnings from labor). With $1,000,000,000, you certainly can get a senator. For an example, you can look at the Wisconsin Foxconn debacle. [1] This is the type of leverage over government that billions of dollars can buy. It is legal.
I certainly agree that there is some concentration of power. The Koch brothers and Bill Gates have a lot more influence than I do, and I would guess more than you do too. But how much more, exactly? It doesn't seem like all that much, to be honest.
> It's quite easy to see how wealth inequality is corrosive: make a list in descending order of wealth inequality by country, and look at which countries are where on that list. There's some noise, but for the most part, well-functioning democracies are concentrated at the bottom.
I think you're confusing correlation and causality, there though. Certainly in autocratic societies, you're going to have huge wealth disparity, because the rulers are rich. But the causality is flowing from autocracy onto inequality. I don't see much evidence that inequality causes autocracy, though.
