I think it’s fine for dads to be a SAH parent. Of course it is.. But I don’t think you have a realistic view of how this works! You think women must be pleased by gifts of jewelry? You think the money earner is entitled to be served sexually by the house spouse? As if sex were a payment instead of a shared intimacy? Also, regardless of who stays home, you still have the issue of figuring out how to do it on one paycheck.
