I don't know of any Statistical facts about Uni's economic breakdown, but I remember in US History Mr. Sutton starts out his lecture on the "Wheel of Respectability" by having us raise our hands based on what class we are, in my hour all but 2 said "middle class", the exceptions of one being "lower class" and one being "upper class". Wealth in the eyes of the beholder. In contrast to the community I am from, and the income of my family throughout my life, my family's current income seems like more money than we could ever need. But in reality, we still qualify for 50% need based financial aid. And based on my observations and conversations, many Uni students wouldn't qualify for financial aid at all. To me, having that much money is very wealthy, but not to them. Although the article is about dealing with the expectations of upper/middle class, I would like to draw the parallel to the same type of pressure in lower classes. In my reservation community, you are successful if you have a steady job with either just high school, or a local college degree. Because so many people drop out of high school, and most stay within the community, the bar is set at that line of success. Going above it, has the same type of discomfort that is expected from someone in the upper class who goes below their expected level of success. Breaking the social barrier is by no means easy, from either direction you start at.
