Less of course. But the socialist left thinks the answer is more.
Oh, I don't know about that.... The USSR was big on authoritarianism - the party leaders were defended no matter what they did and where considered to be infalible. Anyone who dared disagagree with the party line was branded a traitor, and the media constantly praised the leaders and attacked their critics.
They were led by an ideology which had no basis in reality, but instead insisted on the delusion that you could bring about a utopia through millitary force and ideologically indoctronating the populus.
Socialism is inefficent, but Authoritarianism is evil. We should learn from them, a single party state is doomed to failure - to succeed you must had dissent and the crucible of open debate. The current 'republicans' (who discrace the name of a once noble party), don't seem to realize this fatal oversight.
