Sous de gais i lesbianes

Interessant estudi ("The truth about lesbian & gay economics") via Freakonomics sobre els sous dels gais i lesbianes. Les conclusions, curioses:

Els gais guanyen menys que els hetero:

"Gay males have more education than straight males, but they do not choose male-dominated professions as often as straight males do. In fact, they choose female-dominated and/or service professions much more often.” Gay males also work fewer hours than straight males.

I les lesbianes, més:

Lesbian women, by contrast, work more hours than straight females and are “overrepresented in male-dominated professions that pay better than female-dominated professions.”

I sobre tot això, una frase que deia fa uns dies de Bertrand Russell: "There is much pleasure to be gained from useless knowledge"
