The problem with communism is, that everywhere it was introduced with some military power and everywhere there is/was some kind of dictatorship. From ancient times, every dictatorship fails sooner or later. There is no long term stability without freedom.
Communism in Poland failed because it was introduced by Soviets = external dictatorship.
When soviets failed, their puppets in Poland failed too.
Don't forget that after WWII, Poland's infrastructure was devastated. The USSR rebuilt a lot of that.
Man, what a bullshit... The only things USSR built in Poland was "Palace of Culture" and military bases... Yes, Poland was devastated, but Poles rebuilt it, nobody else...
Ok, Poland got part of Germany, and lost territory on the east, but before Poland got it, Russians took away every single screw from factories there. Wroclaw (Brezlau) in 1945 was a desert in very essence of this world.
That probably Soviet Union subsidized all eastern block countries with profits from oil.
Hm... where have you been between 1989 - 2000? During this period Russia had even bigger problems than Poland, Czechs, Hungary... It is obviously quite contrary to your statement
and that is why putting Communism there was like Comrade Stalin said, putting a saddle on a cow.
what can you say then about even more agrarian Russia in 1917? :-)
