The same is true for whites. Controlling for differences in housing costs, an increase of $10,000 in the mean income for white households—about like going from South Carolina to California—leads to a 13 percent decrease in spending on visible goods. “Take a $100,000-a-year person in Alabama and a $100,000 person in Boston,” says Hurst. “The $100,000 person in Alabama does more visible consumption than the $100,000 person in Massachusetts.” That’s why a diamond-crusted Rolex screams “nouveau riche.” It signals that the owner came from a poor group and has something to prove.
Generally speaking, this makes sense, but their examples give me pause… might it not be that 100k simply goes nearly three times as far in Alabama as it does in Boston?
