In the western world we already have many forms of wealth redistribution. Why wouldn't normal democratic government suffice for communism under right circumstances? You might as well say that the core problem of capitalist west is how to collect taxes without dictatorship. The people choose the government and give it the power to implement policies. Of course implementing communism wouldn't be easy if big part of society was absolutely against it (as civil wars have shown), but if enough people wanted communism and voted democratic communists into power, I can imagine democratic communism happening. If it would succeed in the long term is another question.
It's good to remember that in Russia (and most? other countries that were/are communist) there was never any real democracy. Not before communism, not under communism, and not now. I think the outcome could be different (less authoritarian) if communists were chosen by people who actually lived under democracy before.
Oh absolutely, of course that's the point and it's why Orwell was a democratic socialist. In democratic mixed economies we have some redistribution, and some private property, and some state capitalism all mixed together. In truth all 'western' economies are mixed, not even the USA is anywhere even close to being purely capitalist; not even the most socially minded European economies are anywhere even close to being purely socialist.
USA was financing coups and assassinating anti capitalists in Latin Americans even when they were elected, so just choosing them doesn't work. Capitalist power structure is fine with using violence to keep its hegemony even against Liberal rules.
