There went universal healthcare in all nations that have it. If you think the yellow vests rioting in France over a gasoline tax (among other things) are bad, just wait until you see how Europe burns to the ground over that one. In the US, Social Security has no actual lockbox ("trust fund"), it's a fraud in terms of funding; without perpetual vast subsidies, Social Security would immediately begin to collapse. Medicaid would go away instantly as an entirely subsidized program. About half the US would lose health coverage. The 44 million people in the US receiving food benefits via SNAP would lose that.
The argument is always going to be over what should be subsidized, between conflicting factions. The number of people willing to see all subsidies eliminated is practically zero for political purposes.
