If Capitalism is so bad...

If capitalism is so bad, why has it given so much freedom, opportunity, and success to the people under the system? Marxists say that capitalists have achieved their success on the backs of the masses. Is that really true? Never before in the history of the world have the masses living in capitalistic societies been able to achieve so much and live in relative security, comfort, and well being. I believe that capitalism is the economic engine that supports freedom. Marxists are the ones who actually rise to their power on the backs of the masses. Every Marxist regime has resulted in failure, poverty, and even death for major portions of their populations. The society supported by capitalism has brought more justice to its people than all of the Marxists regimes combined. Except for the minor corruptions caused by misguided people in a capitalistic society, capitalism is the best economic engine given to man. Marxism is just the opposite. It is a scourge upon the backs of mankind.
It seems to be the delight of some to bash corporations and banks as evil, and granted, there are some very unsavory things that happen in the name of profit, like slave labor on the one hand and opulence on the other. It is these corporations, however (not excusing the evils of greedy human beings), that have given many in this semi-capitalistic society the opportunity for a comfortable life if not the opportunity to achieve financial solidity and success. If you want to seek out the truly evil and greedy operators of such corporations, fine, but that does not mean that corporations themselves are evil and greedy. Quite conversely, they have generated the riches that have made our nation the benefactor of a lot of good in the world. We have fought for freedom all over the globe, and have given aid to nations throughout the earth who are in dire straits. What a dark place the world would be without the United States of America and capitalism.
So, it seems to me that Marxism and its little siblings of socialism, communism and fascism, swept into power by waves of liberalism that are the true evils. Just like no person is 100% good, no system without God’s rule is 100% perfect. When comparing capitalism with Marxism, however, capitalism comes out righteous and Marxism ends up being the evil system.
