But what if those people at the hospital have a lot of money? I'd rather disperse it to healthcare workers than give more inheritance to their children.
I mean that's great in concept but it doesn't really help the core problem there will be more older people no longer working(or outputting as much if they do)/needing extra support than the other way around as it was when it was population growth times with the same total population. Not just the ultra wealthy are going to output less or need healthcare more either.
Maybe this is true if you only look at paid labor, but there are other ways in which elders add value to society, as they do a lot of invisiblized unpaid work. Their pensions play a role in supporting the economy, as much as people seem to only think of pensions as a burden to source and rarely as supporting the economy when it gets spent.
