On Memorial Day we reflect on those who gave our lives for our freedom. Capitalism's underlying theme is freedom. The question is freedom from what? In a Capitalist society freedom means having freedom from the initiation of force by others. That's why conservatives tire of hearing new welfare programs to help the "common good". The only way the government can give a $1 to someone is to take $1 away from someone else! That is initiating force against someone to take their money and give it to someone else. But it's not just the politicians in Washington to blame; we as citizens act passive and let them get away with such schemes. I expect the men in Washington to keep acting as they do as long as we remain passive.
