This is an example of "be careful what you wish for". Some areas of the country are bemoaning the loss of gasoline tax revenue as people drive less, and drive more fuel efficient cars.
Pundits say Americans don't save[1] enough, but what if they 'saved' more? The fear is that the economy would collapse from a lack of consumer sales... oh wait, we are seeing something like that now as people and companies hoard their cash....
[1]what exactly is the definition of "saving". Interestingly enough, it does not include capital gains, or (usually) 401Ks, or equities (stocks and bonds), or not having a mortgage on your house so there is home equity. Usually, savings is just what you stuff in a bank. However, keeping all your wealth in a bank is a poor investment strategy overall, thus Americans don't do it-- which makes American "savings" look bad (it is also made to look worse by not removing retirees from the population of savers-- retirees are generally spending the money they saved! This is a major reason WHY people save assets after all, to spend during retirement! It boggles the mind how poorly understood this is.)
