This ain't political.....it's just Mathematics. We are already running Trillion$ annual deficits in and extremely strong economy. What the hell do you think is going to happen when we have Medicare for All and Guaranteed Annual incomes along with huge increases in taxes which will cause a shrinking economy. Answer: Bankruptcy of the Government by repudiation of our debt OR Destruction of the US Dollar because of massive money printing. Historically, politicians always choose the latter and probably will in this case.
The scenario above could occur without movement to Socialism unless we get our financial house in order but more massive govt spending programs will speed up the timetable significantly. It not a question of if but when and it won't be pretty.
