Capitalism is an economic system and itself isnt evil any more than a knife is evil. I know this sounds like I am being picky but believing that capitalism is evil goes along with the idea that capitalism is like a person and it isnt. Capitalism should be viewed as a tool which can be used for good or bad just like a knife.
Humans cannot live in society without rules. There is a natural tendency to look out for one's self. But to live in an orderly society, humans must some times sacrifice what's best for themselves to make the society function for the best of the society.
Also, it must be clear that when we say capitalism needs to be regulated, we mean "for the benefit of society as a whole" and not for a select few. Our capitalistic based system currently has lots of regulations, but they have been modified to benefit a very small, select few.
The SCOTUS did our society a great disservice in the Citizens United decision where they ruled that our Constitution restricted us as a society on how much we can regulate our capitalist system. They demonstrated their enormous power to overrule the Congress and the President. IMO this is out of hand. The SCOTUS has too much power (but that's a discussion for another day).
The argument that the capitalist (oligarchs) cant be regulated by society because it's not "democratic" is bogus. Our democracy isnt inherently laissez-faire. We as a society can and must control our democracy and economic system to benefit society as a whole and strip the oligarchs of their power.
Capitalism isnt evil, we must take responsibility to control it, by whatever means necessary.
Other than that, have a great day.
