> They only people that I've ever met that don't have insurance have enough money to pay for it
Then you haven't met enough people.
> The poor are already covered by social programs.
That's a joke I hope, but it isn't at all true. Social programs tend to only cover emergency care. If you get cancer and you're poor, you're fucked and doomed to a slow death because emergency rooms don't do chemotherapy. Anything that requires treatment but isn't immediately emergency life or death and you're screwed. Do you actually know many poor people?
