Economist Steven D. "Freakonomics" Levitt reports
"The fee for a trick varies with the type of sex act, and prostitutes seem to discriminate across clients in order to maximize profit. White men pay $8 to $9 more per trick than black customers, with Hispanic clients paying some amount in between. When bargaining, prostitutes will usually offer a price to a black customer but will make a white man throw out a number first. Repeat customers pay slightly less than new customers."
Too bad prostitutes can`t afford to pay for Malcolm Gladwell
to address them, because Malcolm would explain to them that, like car salesmen, if only the whores understood that they were unconsciously discriminating, they`d stop leaving money on the table.
