Not preaching, just stating facts.
I was taught about the horrors of Eastern Europe when I was growing up. I had many relatives that escaped it. It stuck with me.
I've been living 27 years in that Eastern European communist concentration camp. Indeed, Albania had the worst form of communism, but my ex-country wasn't too far to reach that form, especially in the 80's. My family had the option to move either to Germany or Austria, since my both grandmothers were from those countries, but they chose to stay and hope for an intervention from the West. That never happened. My theory is that the West left in purpose the communists to expand, as an experiment for future purposes. Then they destroyed it. They picked what it worked and deleted what it didn't work. What it works is the fear, spreading fear among the people is the easiest one. In Romania, after the WWII, the new government, imposed by Kremlin, required to all people to surrender their guns, since there was no more war. Some people didn't surrender the guns, they didn't surrender themselves to the new communist order. They preferred to fight for the freedom. They were called terrorists, anarchists, they were called the enemies of the country. Many of them died after short fightings against the militia (former police) or army. Some of them realized that they're fighting for a lost cause, and either chose to surrender, or left illegally the country. Ok, I've been talking too much already and I don't wanna bother y'all!
What it didn't work was the nationalization of the companies. It's hard to keep under control a centralized economy. It's much easier to let 'em the way they are now and control them through taxation. That's what Yugoslavia did. Only the large companies were nationalized, the small ones were private. And it worked. Anyway, Yugoslavia had the lightest form of communism, it was a country open to the West.
