Having a balanced age pyramid is not a Ponzi scheme: it's natural and healthy and as old as hunter-gatherer society itself. You want youthful energetic members, optimistic innovators and learners; middle-aged strong leaders, fighters, and innovators; and you want elder wise-people. There's actually a reason humans are long-lived past menopause: the old/grandparents provide a lot of value in social groups. The one way I agree with Ponzi Scheme... in the USA currently, at least, there's been a massive transfer of wealth to Boomers from everyone else via SS, Medicare, pensions, and all the cheap education and services that have since evaporated. I doubt these conditions will exist for anyone else...Boomers really got an amazing deal.
