"A rural kid who makes it to a university will almost certainly have to work an almost full-time job just to cover their living expenses, books, tuition, rent...etc."
The point of the article is that this is not true and almost no one knows it! If you go to Harvard/Stanford/MIT/etc -- basically any of the Ivy League, top LACs, or a few other elite schools -- and your family makes under, say, $60k/year, your tuition/room/board/books will be absolutely free. All covered by the school. No crippling student loans, no expectation of you working a job while in school (except maybe 10hrs/wk of cushy work-study for spending money). Even if your family is a bit wealthier, it's still the case that for most middle-class families the cost of an Ivy League education works out to less than the cost of the local state school. Very few families know this.
Is there culture shock? Sure, of course. That's part of the point -- for both the poor rural kids and the rich urban kids, and everyone in between. But at schools with the resources to do diversity right (which, sorry to hear, doesn't sound like it includes Virginia Tech), the shock is only cultural, not financial, so the full college experience really is accessible to students from any background.
