Maybe all the new money ends up in the hands of the rich elite, who just funnel it into the stock market, so it never really ends up inflating real assets. I could totally buy that these are the types that care the most about making the slider go to the right, and don't necessarily spend much of their money (or have so much of it that they already spent it on everything they possibly could).

Ding ding ding!

Lets assume the inflation remains contained in the financial sector. What does this mean e.g. for a young family with no inherited wealth, with average income and savings rate? How should they invest their savings? Isn't it more difficult for them to "break even" (in the sense that their capital income offsets their share of contributing to others capital incomes) than before the asset price inflation?
