It was many years ago, but I recall seeing some kind of study with a considerably large n and it basically boiled down to male doctors marry secretaries, schoolteachers, and nurses and female doctors marry other doctors and CEOs. There is definitely some kind of sex-related factor controlling for how important partner income is viewed to be. What I haven't seen is any data on same sex relationships. Are men as indifferent to a male partner's earning potential as they are to a female partner's? How about for women, do same sex attracted female doctors also prefer other female doctors, or do they pair with female nurses and secretaries?
