Too bad Japan decided to save the banks in the 90s crash, and drain their citizen's cash savings by keeping interest rate at 0%. Fast forward to present day where the savings rate is close to 0%, and they have 200% GDP public debt.
US is trying to do the same thing, but alas, it won't have the same effect as Americans have a negative savings rate, and dollar will suffer massive inflation in the process, dooming 60% of the population that live on less than 40k a year.
