What, exactly, was promised to population when Romania (for example) switched to capitalism and opened its borders?
Don't have actual insight here, but 'progressive' to a soviet bloc communist would likely mean 'ultra communist' e.g. hard line stalinist..
Their economy has increased in size by roughly five fold since they switched to Capitalism, with zero population growth. They've gone from a GDP per capita of sub $2,000 to nearly $10,000 in that time. And it appears likely set to continue growing nicely in the coming decade. I'd be willing to bet that in another ~15 years they'll get to near $20,000 per capita, generally something closer to where Slovenia, Slovakia and Czech are today.

Personally, I avoid it.
