bullshit. Not one society considers prostitution an honest living. It may be legal but certainly does society in any country consider prostitution immoral and dishonest. Or why do you think even in the Ukraine, Thailand, Russia, or a country of your choosing there are millions of women who work at 1/100th of 1/10th of the potential income whores generate, toiling in factories or other low paid jobs.
I used quotes on "honest living" for a reason, in the countries where it's legal they pay taxes though.
