Low interest rates are basically propping up the finance industry. The cheap money that banks can borrow from the Fed is not going to end up at yours truly, it will only end up in investment shenanigans. In addition, low interest rates also kill savings for poor(er) people - this is something that's a real problem in the European Union right now. Banks offer their customers sometimes negative rates on their savings, and no "conventional" savings accounts hit even inflation percentages which means both poor people and "rich-ish" (=not poor, not rich enough to be able to risk money on the stock markets, but rich enough that their banks charge negative interest) effectively lose money.

The short of it is interest rates are a tool used by the Fed to attempt to control the rate at which people and institutions take on debt. Too much debt = recession. Too little debt = recession. I'm greatly oversimplifying here but Ray does a fantastic job explaining things. If anyone wants to dig in deep I highly, highly recommend you read this book.
That model is Japan, no?
