This article is all about the deprivations that poor students experience in relation to rich students. I am merely pointing out that studying sociology is an ineffective way of alleviating these deprivations.
I missed the paragraph in the article that discussed how much happier they were than everybody else because they weren't pursuing money, but that is certainly another topic that can be discussed.
I do, however, think it odd that you can walk through a poor, violent ghetto and find a family who has a son that scored 1500 on the SAT and went to a good college. Maybe he is pursuing something "more important than money", but it would seem that money would be really important to someone in his situation.
"Following your dreams" is important, but it is foolish to dismiss the value of avoiding material deprivation and being financially independent.
