Ah, but what if the reason women are in lower paid jobs is because if sexism?
The case has made it through preliminary hearings and is now proceeding to a higher court; if they win a massive precedent will be set, allowing for claims of gender discrimination at the level of entire industries and vocations.
(I think it's totally a fair claim.)
If I decide to groom my dog myself, can I expect a lawsuit down the road for my non-consumption of professional dog grooming services if any dog groomer is a member of any minority class? After all, you can't be sure that I'm just a cheapskate who likes washing my dog; I might be racist/classist/sexist.
In case it's not clear, I view the decision to consume in a free market to be a free choice and not subject to judicial review.
