You're dreaming here. I can promise you'd bore sorely disappointed when it became evident just how few people actually took care of their parents. As for the 4900 years of recorded history, for the most part the number of folks who actually lived to become dependent elderly was a fraction of what it is today. Death quickly followed the end of productivity for the vast majority of earths population for almost all of recorded history. Modern medicine has forever changed that picture.

I guess maybe I’m the exception then. If my parents needed me to take care of them in need, I would be right there. If they wanted me to spring for a Winnebego or a winter house in Florida, they can get lost (although Social Security will spring for that).
Yes - there are a lot more old people...and a lot few children for each of them. That’s why you still have to have a public backstop to take care of them. But there are also a LOT of people who could take care of their parents, but don’t because the state does that for them.
