If you’re trying to look at America from a balance-sheet perspective the problem is very clear. It’s not “entitlements” and it’s not “Social Security” and it’s not “Medicare” and it’s not “health care costs” it’s the existence of old people. Old people, generally speaking, don’t produce anything of economic value. They sit around, retired, consuming goods and services and produce nothing but the occasional turn at babysitting. The optimal economic growth policy isn’t to slash Social Security or Medicare benefits, it’s to euthanize 70 year-olds and harvest their organs for auction.
