This is only an issue because we have set up a socialist pyramid scheme of pensions, medicare and the like.
With people living longer and having less children, a system where people get to retire at 65 and be supported by the working population is simply untenable.
Yes, it is. Another part that's not going to work much longer is non-working people's being supported by the working population their entire lives.
The modern social-welfare state is an experiment that has failed. The outcome of the failure is not yet evident to most voters, but it's going to kick people where they live "soon," in global-history terms. Those who are old (70s-80s) now may not realize what happened, but many of those now 50s and 60s may find themselves "lives not worth living" a lot sooner than they expect.
