To try to counter the effects of the recession interest on savings was lowered for one reason so people wouldn't sell off their stocks quickly without enough buyers. Saved the stock market, screwed savers who want to prepare for the future.
In a hyper inflationary scenario, the price of stocks goes up just as dramatically as everything else. You’ll be seeing the Dow at 100,000 and it won’t mean a damned thing when rent for a 2 bedroom flat in an average part of town costs $6,000 a month, and bread costs $7 a loaf - on the way to $60,000 a month rent at $70 loaves of bread.
