More household work was done in this era, before grocery stores sold prepared food, before washing machines. And more people lived in less square footage, with grandparents living in the home, less privacy and autonomy. I don't know if we've made the right trade, but it's not the case that a single worker's income was paying for the kind of lifestyle a family of four now has.

How is this relevant? The houses built in the 60s aren't affordable either. Look at median income and median home prices. You're telling on yourself. Average families aren't buying prepared food and they have a washing machine from the 90s they bought on craigslist. There's a 90% chance if you are on this site, you are not average. You are a part of the haves and you need to consider that you are living a very different life from the average American, which all this productivity should be helping but fucking clearly isn't.
