The college kids who have jobs so they have more pocket money to spend on lifestyle stuff (i.e. beer) is exactly who I'm talking about when I say "most people who do that don't suddenly find themselves among people who significantly higher up the social ladder"

The college kids with work-study jobs in the kitchen, get financial aid, furnish their living spaces with office furniture the school discarded, and whatnot are the ones who move into a different social class when they enter the workforce.

I think we're agreeing here.
