It feels a little bit like the author combined two different articles. Both are good (I don't mind anti-capitalist rhetoric), but the tone change and continuity break is hard to miss.
Just dropping all of the communist bits and stating /how/ and /why/ capitalism pushes optimism would give it some intergration. It would at least fit in as a "novel or less commonly listed flaw of capitalism" instead of just including the list of top down beliefs as articles of faith.
I really doubt what you are saying here. Eastern Europeans are just as capable of logical trains of thought supported by compelling writing and evidence as anyone else in the world - which is very different from this article.
