Describe a person who supports private Social Security AND and government-run Medicare for All

[Senator Incitatus]

This isn't quite my position, but in a vacuum, I would definitely support something like Medicare for All (i.e., universal single-provider or single-payer) more strongly than any sort of Social Security program.

The only argument against this position which appeals to me is the relative costs of managing the two systems. But this is an afterthought and generally speaking, upfront medical coverage and a general ethos of healthy-at-every-age is strongly preferable to a program which could be described at worst as a Ponzi scheme and at best as the epitome of "managed decline."
