You will depend on today's children to uphold society and care for you in your old age, so asking you to contribute to their education is perfectly reasonable
not necessarily true. I'm an antinatalist planning to kill myself once I get too old to take care of myself on my own. There are many people who are childless because they believe that making children to take care of our selfish needs is horribly wrong.
There will be people managing your deceased body.... and remaining posessions.
You will require children to push you off the building when you want to die though.
How about we fix that problem instead by eliminating the Ponzi scheme that is social security?
Older generations depend on the young for everything not just social security.
