Thanks. I've tried to explain this concept for years, but didn't have a tool to work from.
Perspective-wise, though, the theft isn't just from people. It's from the planet and the future of our grandchildren who will need the resources that the 50 trillion represents if it had been left in the ground instead of building phallic symbols and making war and feeding people who contribute nothing to their places except mouths to feed and papers to write about new ways to 'get rich'.
It isn't only the disparity of incomes that is the problem: it's the fact that humanity doesn't pay its way in nature. Our entire economic structure is backward, not just unfair.
