Is that really true though? If you mean that you can't have a houswife as a character on your show that very obviously isn't true. If you mean you can't make a show where a character aspires to be a housewife, I'm not sure I understand what the narrative purpose of such a story would be. Becoming a housewife isn't really an aspirational achievement in the way having a prestigious career is, and I don't think it's a story many are really interested in, nor one that would be easy to tell in a manner that doesn't seem forced. There is certainly a lot of media (both in the past and today) where a woman aspires to romance or marry someone, and domestic fantasy is a common element in those, but that isn't really specific to becoming a housewife, and the romance is the key aspiration in those.
It also doesn't help that maintaining a family on a single income is not economically viable for most people anymore. People want stories that relate to their own fantasies.
