The richer people, when they get another $100,000, or another million, or 10 million, don't tend to spend it as much as the poorer people would if they got another $100 or $1,000 or $5,000.

In absolute terms, we may have to look at restricting the number of flights people take.

Instability mostly comes from the interface between the fact that the banks (or shadow banks) can create credit, money, and purchasing power in infinite quantities if we don't constrain them, and the fact that credit is primarily created to fund the purchase of urban real estate and land, which is somewhat fixed in supply.

In economics, when you put together a highly elastic thing and a highly inelastic thing, you create extraordinary potential for turbulence, volatility, and for unstable prices.
