Are you arguing that unions lead to communism? While Europe has a rich weave of social-democratic governments, that would hardly constitute communism. In fact, I'd daresay actual communist parties in Europe with any real power are a distinct rarity.
No,my point was that certain power structures encourage corruption.
Hell maybe they all do. Maybe that is why modern day democracy actually works (checks and balances) and has very little to do with comunism vs capitalism.
