as it takes a magnitude more energy to refute bullshit than to produce it, i'll be brief.
1., the complete soviet block collapsed due to its economic system and policies. growth, consistently from 50 to 80s, higher than in the west? are you delusional?
2., the "saurer regen" was a) never that bad and b) still tackled and fixed. what exactly did the east ever fix?
as someone who travelled into the old eastern block due to my heritage i have to say that your revisionist bullshit is deeply offending.
