Toujoursdan found this report (PDF) on LGBT poverty from the Williams Institute of the UCLA Law School. Among its findings are considerably higher levels of poverty for gay families and for lesbians of color. Those gays who are neither lesbian nor of color are not that much better off either.
I've always felt that "affluent gays" was a big canard, up there with "rich Jews." The rich Palm Springs circuit party crowd is a very visible, but tiny minority of the LGBT population. Most well paid LGBT professionals are in medicine and technology. High tech companies are usually very gay friendly because that's where a lot of their talent comes from. Most other gay men, especially the young, are in famously low wage jobs provided by retail, hospitality, restaurants, and arts and entertainment. And this has always been true. All those boys out for a night on the town at the clubs and party circuits are probably living 5 to 6 to an apartment in New York, LA, or San Fran; pooling their low wages to make that night possible.
There are a lot more gay men in blue collar jobs in industry and trades than most people imagine. They have been hit very directly by the current economic downturn.
Lesbians face a double whammy of the wage discrimination against women built into the economy, and homophobic prejudice. Also, there are no charming lesbians on teevee like there are charming gay boys to soften up the social resistance in the office (though that creates its own set of problems).
Those who face the worst employment discrimination are transexuals. So many once turned to prostitution because there was no other work. Some businesses and professions are beginning to open up very slowly and reluctantly, but it is still incredibly difficult for them.
