And those choices might be prioritizing children, housework, elder parents, disabled relatives, wiping bottoms. There are men who do that, but if you consider the disapproval of a man who doesn't "support his family," and of a woman who "is a bitch and doesn't go along," it's not hard to see that those are only "choices" to the particularly strong-minded. Or the single.
A single woman, with no family encumbrances, probably still earns less than a single man, with no impact of "choice," other than her choice to be a woman.
