FAYETTEVILLE, Ark., May 15 (UPI) — Prostitution is illegal except for a few areas of the United States, but some educated women work in the sex industry by choice, researchers says.

Jennifer Hafer, a doctoral student, and economics Professor Amy Farmer of the University of Arkansas say contrary to conventional wisdom that women enter prostitution because they are desperate — they need money to pay bills or buy drugs — many educated and affluent women are making a rational decision to enter certain segments of the “world’s oldest profession.”. . .
