Better yet, close down all hospitals. Close down public schools, stop building/repairing public roads. Disband police and military. Eliminate manufacturing (it is in the process). Abolish all environmental regulations etc, etc ....
In a few words - make USA so unattractive place so nobody will come.
The reason Socialism always fails is that it attracts an unending supply of parasites, who suck the life out of the productive class until the producers can no longer sustain the society.
Your snide "close down all hospitals"? It's happening here. Emergency rooms are closing because they cannot cover their costs. What are replacing them are hospitals without emergency rooms where doctors can send patients for surgery without having to subsidize non-paying parasites
Your snide "Close down public schools"? The public schools are collapsing. Parents are sending their kids to private schools, or home-schooling. I'm homeschooling my three kids because I'm unhappy with the public schools quality
