Totalitarianism has the same end state whether it comes from the left or the right. It always results in suppression of the truth, broken feedback loops that lead to poor decisions by government, economic failure, and finally either bloody repression, war, or revolution.
It’s possible to move through this to a place of stability. After all, China only had to kill 15-55 million people in the Great Leap Forward and a couple thousand more in 1989. Today they are fairly stable and prosperous, even with tight controls on information. Perhaps the UK will have a similar path!
