The article is true if you limit the definition of “good investment” and “wealth-building” to mean rent appreciation. But if you take a broader definition of investment (as in a farmer invested in a tractor, or a contractor invested in a pickup truck, or a property owner invested in improvements, or a landlord invested in buying an underpriced property with an unusually high capitalization rate), then it is counterproductive. When people talk about housing as an investment around the country, how often are they referring to zero-sum rent increases, vs. how often are they referring to capital expenditures that expand the pie? And how do we get people to celebrate one type of investing (capitalism) instead of the other kind of investing (rentiers).
