The Fed provides stability around the USD market. It deploys a wide variety of polices that attempt to manage inflation, deflation, liquidity, and overall confidence in the USD. Without this stability the USD would be significantly less valuable as a medium of trade, a store of value, and as a tool for reconciling debts.
yes, but that's why it doesn't just "print money". the fed is never going to simply print money to pay off debt because that would necessarily clobber inflation and dollar value policy. I'm not sure why people are downvoting this :-/
