They mean they will never own a home in two of the wealthiest cities in the USA - San Francisco or New York. There’s a few other really expensive cities as well. It’s really easy for most properties to list for 1 MM min, even a 3 bed 1 bath house on a quarter acre lot.

The solution is easy, don’t live in an expensive city. Or inherit property from relatives who lived there 50 years ago. Or have a rich spouse.
