This also means that people spend less until they get to that cash safety. Yes, they will be able to buy things later, but in the meantime they are not, and an economy based on money flow cannot get better until the flow gets bigger. Also, a few years of saving money will change the spending habits, and there is no way to switch back to spending more money immediately. Nobody will say "hey, I got enough money now, let's go spend!" The saving need came as a shock when the banks collapsed. The only shocking way to get people back to spending more is winning the lottery, but that's not a group option.
