Morally, caring for the sick seems like the right thing to do, but it's like when I hear Bernie Sanders call for "free college education": he doesn't mean free, he means the wealthy subsidizing it for others.
Universal health care implies just distributed costs, but the focus should be on bringing down costs so the payments don't have to be so astronomical.
For example:
-Nurses could do a lot of things doctors do now, and for a lot less money, but MDs refuse to cede any authority.
-Medicare should be allowed to negotiate drug prices.
-Hospitals should pre-publish costs upfront before you accept care rather than saddle you with 100K in bills later on.
All of these things would help bring down cost but for political reasons we don't do them. Instead it's just about making wealthy people (which, for the record, I am not) pay more to cover for it.
Even if caring for the sick is just it shouldn't be accomplished just by a wealth transfer (to be fair, the ACA had some provisions to bring down the cost of care, but not nearly enough).
