“How do we undo that?”
It will undo itself, when the inevitable decline in quality of life that always accompanies socialism / communism occurs. The problem is that this is a long process, and many people will be hurt before reality sinks in. Is there another way? I hope so. Depending on the day, I sometimes believe there is, and sometimes not.
Well, that is what I figure, though I wish I felt it would happen some other way.
