This is a naive view. Life under the Soviet Union was horrible. Talk to nearly everyone who lived in fear that their neighbors would rat on them.

That affects everyone.

They're probably referring to modern day countries that remain controlled by Communist parties officially. However, these went through a decades long process of privatisation to get where they are today, and there is no guarantee they won't backpeddle.

The horrible life in Soviet Union was due to horrible governmental policies, which are not unique to authoritarian governments. Liberal governments have their fair share of bad policies.

I wonder why people voted for those bad Soviet policies.
