It is something of a myth, though, that Americans "don't save." Most Americans have medical covered through "forced savings" at work; they have retirement handled through "forced pensions" and Social Security---rightly or wrongly, they contribute money that they might not otherwise, and that IS a form of savings; and homes are usually a reason people save---but if mortgage interest deductions makes it logical to purchase homes on time, the incentive to save for that is gone.
When you factor medical "savings," pension and SS "savings," and the mortgage interest rate factor (and I have seen a study on this), guess what? Americans save about as much as everyone else. Now, granted, some countries have "forced" savings that exceed ours, but usually not private medical or retirement plans. If the main three things people "used" to save for are now handled by "forced savings," saving does not become that important. My parents saved to buy 1) a house; 2) to retire; and 3) for medical emergencies. Well, those things are all dealt with differently now. I'd prefer to go back, but it is delusional to pretend that the "forced savings" do not exist or are not having real economic effects.
