Perhaps this is just my European wallet talking, but $50k/y income = rich people. I'm sure there are states in USA where this is also true.

That sort of a change would totally crash tax income?

I'd rather focus on ripping cars out of cities, promoting mixed use zoning areas, removing regulations on food service (which is the reason small American food vendors need food trucks, instead of "street food" like the rest of the world.

The disjointed, car based, child hating society we have is a big problem.

I’m happy if the mail comes on time. I don’t think the government could properly manage these broad sweeping programs especially with radical changes to the legislative and judicial branches and elections.

Nor do I think you’d be able to get the states on board with this much radical change. Everything sounds ok on a surface level but rather than thinking pie in the sky, pragmatism would be needed on just the most important issues such as a universal health plan or education plan
