Because it isn't simply about material wealth. Money is power. People with money have a far greater say in shaping our world, and have more freedom. Conversely those with little have little say and little freedom. Even the part of our society that is supposed to be egalitarian regardless of wealth or station, our government, is ruled by those with money. "One person, one vote" means nothing in a society where money buys elections and elected officials. It's about having a fair and free society. Would you rather have a gourmet dinner every night in prison, or a PB&J in a free and egalitarian community?
