Looks like HN is obssessed with physical attractiveness. Humans are interested in other things about their mate as well: intelligence, for example. In surveys, nearly everyone reports that they would like a mate at least as or more intelligent than them. And we rarely have good, direct signs of intelligence, so we use things like language, humor, &c. People also care about in-group membership, social class, and many other things. There is some correlation of physical attractiveness to income &c., in that more attractive people do make more money than less attractive people on average, but I would need more evidence to say this correlation is strong.

Look at that chart: the main way straight people meet their partners is through friends. In-person meeting pairings vastly outweigh online meeting pairings. Back in the 1940s, people meet through friends, through family, in elementary or high school, or by being neighbors. I shudder to see the rise of "at a bar", but online dating is a huge, huge improvement.
