Honestly, this is just the modern version of a process that has taken place since the beginning of time. It's called assortative mating. Basically, people tend to end up married to people who are of an equivalent class/quality/caliber. Now there is a dating app which augments the role of country clubs, private schools, and expensive neighborhoods in enabling the elite to find each other. NBD. IMO, a much more troubling development is the way that the rise of college education in the 20th century has systematically pulled the cognitive elite out of most of the country and concentrated them in urban centers (where all the high paying jobs that demand elite cognition are located). Whereas the elites have always lived an existence far disconnected from the rest of us, now the upper middle class and lower middle class are similarly disconnected from each other.
