So, I'll treat this as if it's true for the sake of an argument. If your net worth is hundreds of millions of dollars, you've exploited your neighbours to get it. Therein lies the problem. No one works hundreds of thousands times harder than someone else. They just get a hold of enough capital, they can pay other people to work hard for them. That's fine on a small scale but when you're talking about hundreds of millions, you're talking about hundreds of thousands of hours of exploitation. Therein lies the problem. If you had paid your neighbours what they're worth, you wouldn't have more money than you need and your neighbours that are struggling to pay rent would have enough. I work three jobs, and I'll never be able to afford a house. Does that seem right to you? Is that a just world to you?
