The coupling trends that seem interesting to me would be hard to study. In the gay community it used to be really common for white collar and blue collar guys to get together and that really helped form a power couple as one could handle the rough stuff and repairs and the other could handle the money and the paperwork. Nowadays that still happens, but it is rare because there is so much social conflict that the blue collar gays are more likely to just marry women and have men on the side because that is so much easier and the white collar gays stick to themselves. Among straight people in the San Francisco Bay Area I have noticed a trend of wealthy techies, mostly but not exclusively men, getting hitched to ordinary folks like teachers and mechanics. It seems to mostly work out well as a way of dealing with the housing crisis, but at a basic level it seems like a deeply unbalanced and unhealthy situation. Just some potentially related anecdata. Mileage will vary.
