I don’t agree with your final assertion.
Liberalism is the political expression of the worldview/religion of humanism,
which believes man is the sum of all knowledge,
and inherently, those alive today are smarter and more capable than anyone who ever lived before.
Therefore, though all those collectivist tyrannies failed in the past,
those alive today will “do it right”, because of their superiority.
“...those alive today will “do it right”, because of their superiority.”
Hmmmm...maybe THAT’S what the Germans told themselves when they began building furnaces to solve their social problems.
