I've spent time in socialist countries and it was miserable. And the closer a country gets to socialism, the more miserable and poor people end up being, the more their liberties end up being restricted, and the more corrupt government becomes.
Most libertarians would be happy to turn back the clock on government regulations and government taxes to more traditionally American levels, for the simple reason that the current situation is not sustainable. Progressives are so much into sustainability, why don't you start with finances?
Define "traditionally American levels" - taxes today are lower than at any point from 1933 to the mid-eighties, yet median income, as a percentage of GDP per capita, has been trending downwards since the '80s; meanwhile, CEO pay has skyrocketed. Do you call that sustainable?
