I do not know the family history of those in this study, but family and community influence has to be a factor. You can have access to the world, yet if there are no models as to how to take advantage of this access, you may as well not have any. People want to blame the degree choice, though I feel a terrible issue within business and healthcare is that you have a lot of people in these fields chasing money with no humanity to fuel that passion. Meanwhile, if you do pursue an education in something geared towards repairing humanity from a cultural standpoint as opposed to fueling capitalism, you can be seen as wasting your education.
If society says that aspiring to repair society over capitalizing from it is a loser's game, then we have all already lost. There are no family values left in the United States anymore. If you try to hold on to some, watch as they get diluted by greed or a desperate attempt to enter a new class.
But everything I am saying is beside the point if you're entire objective in this society is to make money.
