There are some assumptions here: 1. You need money to survive - Nope. Money is a medium to exchange for goods. All the money in the world can't save you if there's no food/water. 2. Starting a business solely on personal gain - A million dollar business, I assume, is you're example of a successful business. Though it will be true for a lot of people, please pose the question "Would you start a successful business if it would save millions of lives and billions of work hours?" 3. Supporting people that didn't need to do anything - There's an assumption that people that don't need to support themselves will be unproductive. Is this neccessarily true? Though it might be a small fraction of the population, there are people's interests that they pursue that would greatly automate jobs or help their society. Theoritical work that people pursue are abstract, but the research findings could give great insight into physics, biology, social dynamics, etc. The heart of your statement is more philosophical in why communisum won't work. But would a purely capitalistic society be better? Where you know that near every action is derived from personal gain?
