Because printing trillions of dollars and throwing it out of helicopters is highly inflationary and with zero percent interest rates, the only place you can hope to retain the value of your savings is in the stock market.
Bingo. Right answer.
You win the prize for the day!!!!
I think there's a lot of truth in that. I think the reason we haven't seen much inflation from the loose money policy that's been pursued for some time now is that the consequences are being absorbed by the entire world economy, not just the U.S. But if we keep going the way we're heading, we'll be seeing some palpable inflation before too much longer. You can't get away with this sort of thing forever. The piper will be paid.
