Socialism in the US:
Public Services and Infrastructure: Police, Fire, roads and bridges, water, waste, garbage collection, and the latest: Data Centers (at least on the funding and such). I don't hate the DSA ideas around managing data centers as utilities.
Social Security, Medicare, Medicaid, Unemployment, Food - all of these are good in the aggregate but can and should be improved to eliminate fraud, become sustainably funded, and become more efficient.
I am not against Medicare for all.
We will need some form of UBI soon as AI eliminates jobs.
The department of education needs to be ripped out and either replaced or reverted back to the states. Politicians should look at what Mississippi is doing as California is completely failing on the education front.
Adapt or die is the name of the game for civilizations.
