How do we define "not being able to care for one's self"?

Disabled, unemployed, etc.

Why health care and not food? Water?

Health care should be non-profit. Corporations should not be built upon illness and injury of others. Water and food need to be regulated in a capitalist society.

Doctors do not deserve to make a profit? Who else doesn't deserve to profit from their labors? Besides RV builders?

Canadian and UK docs do fine. i don't know details. People should get paid for their labor, that does not say the delivery system should be built around corporate profit.

You realize that infrastructure is more the highways, no? The "grid" has always been privately run, excepting the TVA, which has worked pretty well. A lot of eggs got broken in that. Railroads were built by robber barons using essentially slave labor. Tear it all up?

Utility regulation and contract supervision as I said.

How is there "room" for the arts? Seriously. Where does the cash come from to support the arts? taxes The bucket is overflowing. Or do you not see that? As a half baked artist, the last thing I need or want is government "approval".
