According to me, Money itself seems kind of evil to me. Whoever has enough money, he/she doesn't need to worry about the future as they can just buy all the resources and stay happy in thier house. I want everyone to be self-sufficient and co-dependent in small numbers so that we function properly in all kinds of situations. You don't need money for that. You need trust, loyalty, a good skill set, love for your small community. If anyone doesn't agree with me please give me a better explanation on how it is supposed to be.
