Strange thought

There are two groups of people in two different locations. The first group receives 100 pounds of food from their government for the first month, while the second group receives 200 pounds of food. In the second month the first groups is given 200 pounds of food while the second group is given 100 pounds. because the first group received 100 pounds of food more the second month than the first they support their government, but since the second group received 100 pounds of food less the second month than the first they rebel against their government. Even though both groups were given the same amount of food within the same time period one group supports their government and one doesn't. This happens all the time in our society. The real question is why does this happen? Why do human beings pay attention to whether they are given more or less than rather what they are receiving itself. For example, at our school, Cypress Bay, student lunches include a milk carton and a juice carton. Whenever the school is out of juice the student get angry. If the school would have never gave out juice to begin with the students would never get mad about it. Maybe this is the reason some places cannot advance. If their government gives the people too much the people will want more and more, and if they don't get it they rebel. Sometimes I think it might be better for our country if the government were greedier. Maybe this might even have something to do with communism. Tell me what you think.
