THis does make depressing reading. Yet it's not a argumnt in favour of keeping sex work illegal, because that doesn't stop it happening and makes the working conditions worse. Far better to allow sex workers to unionise and prevent their exploitation that way.
(AndI do wonder a bit about that piece. If the brothels are legalized, then the workers in them must be given the same human rights to leave, seekother employment, take legal action aganst mistreatment fom their employers, etc, asany other worker. Otherwise these are not legal workplaces at all. The writer also pretty muh suggests that any woman who reports a positive experience of sex work must be lying.)
