I don't worry much about people who have more than me. I am grateful to enjoy my work and my life. I don't want the government to steal from me and I don't want them to steal from others either. Even in the black and white world of marxists, exploitation of labor just moves from the oppressors to the government. The government becomes the oppressors. It has never worked, it will never work. People are naturally motivated by profit. It's built in. Messing with that or short-circuiting the work-reward system is unsustainable.
