More like they don’t have kids.
They have a lot of fuzoku.
I was in Germany when I heard this. Before I could keep my BIG FAT MOUTH SHUT I blurted out: "Oh how nice! What a lovely thing to allow your daughters to do. What a charming life. Who wouldn't want his/her daughter, mother, sister or niece to be a hooker?
Imagine, there she is, your baby girl, lying on her back, buck naked, with her legs open, with a total stranger who can do whatever he wants with her. Charming! Lovely!"
I finished the tirade by saying that I DIDN'T wonder why so many hookers were drunks, drug addicts or both. Oh well.
It ain't pretty for male prostitutes either.
