The goal of capitalism and democracy is to provide equal opportunity, not equal results. It is not perfect by any measure but nothing else has afforded as much class mobility as capitalistic/democratic systems have. As concerns religion, communism has been able to suppress religion but as freedom has pointed out, it hasn’t been able to eliminate it. Capitalistic systems have sometimes chosen to embrace religion and sometimes ignore religion but they’ve known better than to try and eliminate it.
pokeranger, yes religion has been the source of much warfare and strife throughout history but it has also been a primary source of bringing about order and civilization itself. I think overall it has been more positive for more people than not.
