Scarce examples would be homes in the best school district you can afford near the best job markets. Or the best doctors, tutors, etc. And if the majority of people opt to be in dual income households, then the price of even average products/services will rise so that single income households will have to settle for less.
Humans are status seeking, so stuff is not just stuff. People value obtaining products/services that others cannot afford. The most basic example of this is the common advice to “buy the cheapest home in the most expensive neighborhood”.
Meaning, if you want your kids to hang out with kids of parents who earn at least as much or more than you, then you bid up housing prices as much as you can to minimize the number of families under a give income level that can afford the homes in the school district.
> in fact there is much more stuff for us to buy with our money now, and in fact (all else equal) woman working may drive DOWN the price of good and services.
This is also true, and it did drive down the price of many goods and services, including the price of labor itself. But it can also be true that prices for average or below average product/service decline, and above average products/services to increase.
