Sometimes this is quoted as an international phenomenon. In which case no value could justify changing the rules in one country based on women's disadvantage in another. Introducing a greater level of affirmative action in Australia is unlikely to help a sex slave in Turkmenistan. The fact that group A are bad to group B does not justify forcing group C to give subsidies to group D.
This is an example of feminists trying to take advantage of the misfortunes of others.
Sometimes this argument is made of Australia. In Australia, with relatively easily available welfare, few women are 'forced' into prostitution, but yet anyone can see large numbers of prostitutes whenever they walk through St Kilda or Darlinghurst. Clearly this is a career and lifestyle choice they make for their own reasons. Many women choose to go on welfare rather than become prostitutes. The ones who become prostitutes are not victims of their own choices.
