In America, people have always used the barter system. Although we use money now , the will to trade is the most productive economic model because we have needs. If we would like to drive a car we need oil. I believe oil comes from another country. If we do not trade then we will be missing out and live in the prehistoric days.
I think the capitalists should be taxed greatly because it is the only true way to spread the wealth and bring balance to society and civilization as a whole so everyone could have equal opportunity and not just the people who were lucky enough to be born into a filthy rich family.
