There are plenty of reasons to not have slavery. Capitalism isn't slavery. Selling you on an idea where we can all have happy lives doing what we want and living well doing it will only serve to make you miserable because you're convinced that your job is unfair, it's the equivalent of slavery, and some guy is living well off your efforts. You could improve your situation by working hard, getting promotions, getting training. But you don't want that. You want everything handed to you. Nothing gets done without hard work. But you seem to believe it does.
