When Europe sent people to "The New World" and tons of silver was shipped back to Europe, the result was ridiculous inflation. Historically, when you inject more money into an economy but not more goods and services, not more intelligence, not more real value, the result is inflation. Prices go up because there is more money but not more stuff to buy with it.
I don't know how help you understand how ridiculous this idea is if you think dismissing my personal experience somehow proves my point wrong. It doesn't. The point can be made other ways. I just happen frequently speak from firsthand personal experience in part because it was part of the culture of a very respected list I once belonged to where the standard was 1) speak from firsthand experience or 2) cite your sources.
Put another way, it used to be a mystery: "Why do hotdogs come in packages of 10 and buns in packages of 8?" now you should be asking "Why do hotdogs come in packages of 8 and I still pay the same amount as 10?"
Your claims do not reflect my personal experience, and do not seem to be very well substantiated.
Look at the price of BMW's U.S. entry level 3 series. In 2004 it was $28k MSRP. BLS estimate for 2014 using official inflation is $35k MSRP. Actual is $38k MSRP (under 2.5 percent) for what is for various reasons a lot more car (50 more horsepower, bigger, safer, more fuel efficient). If it weren't for tighter emissions requirements since 2004, inflation in the price of cars would probably be below the general inflation rate.
However, this does not mean that any increase in the money supply will have negative consequences. For instance, if you do not increase the money supply at all and the output and population increase, then you have major problems as well.
In this case we are talking about levels that are easily absorbed by the economy, which is not equivalent to an economy that uses silver for coinage finding more silver than they have in circulation.
This style of reasoning by anecdote is the problem with public debate, it's an appeal to emotion rather than reason. It's really not useful. Statistics are useful, anecdotes are not.
If you do not see the vast difference between the kind of careful investment made by Ycombinator and simply handing everyone money who happens to be a U.S. citizen, I don't know how to go forward with this discussion.
