Doesn't this create a situation where the old rely on their own younger generation to support them?

And therefore inequality between older people who have families (or have families that care about them) and those that don't?

I can see this particularly being a problem for countries like the UK which has long encouraged "upwardly-mobile" people to move away from their towns of origin in pursuit of economic opportunity, leading to families being widely dispersed across a country which, despite its fairly small size, is not especially fast to travel around.
