Has capitalism ruined the U.S and will the lower class people finally fight back?

I just watched the movie/documentary by Michael Moore "Capitalism- a love story" and was completely blown away, i couldnt turn it off and that stuff normally doesnt bother me, it just got me wondering is this part of the problem plagueing the U.S right now. For example i could remember when the Australian dollar bought 65c U.S and now its well over a dollar and they expect it to go as high as $1.80.... Is this why america is plagued with medical problems and such slum areas..... i dont understand and i am just wondering if someone could explain this to me......????????
