people are going to act in different ways depending upon what is in their interest (and sometimes it's in their interest to be "nice" while they are enjoying their money). But individual actors are not the problem. The problem is that we have an economic system, capitalism, that rewards greed and stepping on others to get ahead. It has resulted in the top 1% of this country controlling over 40% of the wealth. THAT is the problem - not whether someone buys you a Coke or not.
