Given this as the reason, does that mean valuations will plummet once that supply slows down? If the best bet now is "things will keep growing while money is being pumped in", how does that balance out in the future?
Hypothetical example:
Today, SPY is 339 and DXY is 92.82.
One year from today, SPY is 500 and DXY is 45. Is this valuation higher or lower than today's?
