Our society is set up so that the rich can prey on the poor, uneducated, the sick, the hungry and fearful. It's set up so the rich are protected by laws while the worker and poor are prey. Some people do not themselves commit the crime. They merely use the economic system for themselves. The crime is that capitalism is set up to allow a few to make millions and billions at the cost of millions of other people's suffering. The great crime is that capitalism only allows for one great. Because that one great will take up all the resource instead of spreading it around to help everyone.
The crime may not be intentional but the crime is there tearing apart people's lives causing suffering of millions while a few get rewarded.
Paul McCartney's and Oprah's wealth is not due to some great and magical effort on their part. It's due to the fact that capitalism allows them to make huge amounts of money off other people's work. Oprah did not do it all herself, McCartney was NOT alone when he succeeded. Yes, Oprah had a tough life as a child and lucked into something that others did not. McCartney developed talent and married rich. But do they really deserve the huge wealth when millions go to bed hungry? If NOT for the copyright laws, if not for a legal system, police system and military (paid mostly by worker's taxes) that enforces copyright and other laws to the point that they hound people to suicide, they would not be as rich as they are. Yes, they would probably still be well off, but they would NOT own the huge wealth they currently own.
Did they commit the crime themselves? Probably not, but capitalism allowed them to accumulate way more than anyone deserves, while allowing others to suffer way more than anyone deserves.
