Say, from the stimulus, is that really a bad thing? When people save, they put their money on deposit with a bank. The bank doesn't just sit on that money. I mean they might for a while, but eventually they have to loan it out because otherwise they are just acting as a giant, well protected, and completely free (in most cases) wall safe for the customer - which costs them money. Is it possible that banks would have so much cash from people stashing their money in savings that they might just stop taking deposits? Or would we just see negative interest?
