No, all my claim really assumes is that people have a better idea about what is good for them than I (or some enlightened bureaucrat) do.
Suppose men do prefer working because they enjoy feeling masculine, or that women prefer maternity leave because they enjoy feeling feminine. I generally accept people's desires as they are, rather than treating them as defective when they prefer things different from me and penalizing them if they don't make choices that conform to my desires.
