Le prostitute non pagano contributi, una volta in pensione le prostitute non ricevono aiuto dallo Stato. Neanche in Cina.

"Sex workers in southern Chinese village mired in drugs, AIDS and poverty
Sex, drugs and AIDS are eroding Gejiu, or 'the Tin City', in Yunnan province. The city has more than 5,400 registered injection drug users, at least 70 percent of whom are infected with HIV. Thousands have reached a stage where their immune system has been damaged, and their HIV has become a full-blown AIDS. Many female AIDS patients still cluster around the city’s Gongren Village (literally Workers’ Village) and sell their bodies at 10 yuan to 50 yuan per service."
