houses have gotten much larger since 30 and 40 years go. They've almost doubled in size since 1980, but adjusted for inflation, are now cheaper per sq ft
That's true, and interesting, but I'm not sure it's relevant. People have to buy the houses that are on the market, and smaller houses tend to get torn down to make way for larger ones. Why tweak the numbers that way and not others (e.g. to account for student-loan debt)?
