Communism is a fraud, actually, like socialism. It's a con job. Socialists/communists never live up to Marx's ideology of equal share in everything anyway, and I suspect Marx wasn't necessarily sincere about that, either. All socio-commies have controlled the means of production and capital, either centrally or via controlled cronies or chosen business runners who obey orders, and the profits mostly go to the communist tyrants and their cronies anyway... and we see this happening in newly-socialized America under Obama, too. It's all a scam, a con, a criminal scheme, and it harms far more people far worse than any capitalist society ever has.
Admit it, leftists who bother to look with open eyes and functioning logical minds. Socialism-communism never lives up to its ideology of a classless utopia that's good for all. In fact, well over a tenth of a billion innocents have been murdered in the name of imposing socialism-communism, from the Third Reich, which was socialist and centrist, to the USSR, to Red China, to the Obamacracy in America now (which will become worse and worse unless it's voted out immediately!). Capitalism in and of itself cannot be linked to such horrible stuff as can socialism-communism because under capitalism there is always freedom, democracy and rule of law... to the extent that it hasn't all been corrupted by criminals, socialist-communists, that is...
Ask anyone who suffered under an openly socialist-communist regime and who hated it.
And naturally, so-called "progressives" will pretend that their ideology isn't socialist-communist. But they're wrong. Either because they're wilfully ignorant and/or brainwashed and/or stupid... or because they're propaganda activists. Sure, many will literally believe that their ideology is all good in intention, and there's nothing bad to come of it if implemented. But when their leaders take political power, the good intentions invariably end up being tossed out the window. This is the inconvenient truth. Socialist-communist movements always end up being used by criminals and evildoers for anti-social purposes, as a matter of fact.
