That said, I do agree with the meta-implication of this paper, which is that it's bad for society at large when the classes don't encounter each other socially at all.

Some people have been hurt or persecuted by their "countrymen" and they'd rather put on a cowboy hat and go have a bbq and a beer than continue hanging out with their countrymen. The issue is you won't see them, because they won't live or hang out in a segregated *-town communities. You may find them in an average home, in some average town, going to average grocery stores and so on.
As another sibling comment mentions, we also all seek out products, foods, and experiences belonging to other cultures/groups. Even without getting into the meta, all of this mixing up is important so that Kelly in Texas can try Pho or John in Minnesota can eat BBQ.
Finally, your high school example, as I got older I chuckle more about the cliques of grade-school and now find myself approaching the jocks that I never would have before to see how they turned out. I've heard that a few times, though I've heard the opposite like you're saying as well.
All in all, both of us have had very anecdotal experiences. We should be careful not to generalize _millions_ based on one experience.
