This is a misleading take on the data. A much better analysis would look at the size of the population who was middle class or upper class. If there is an equal increase in upper class population for every loss of middle class population, that just means that our incomes as a population are increasing. All things equal, both the mean and median would increase in that circumstance. And that's what the data looks like…
> Yes, that is a decrease in the middle class-or-better bucket
Huh? Wat? Ignoring your contradiction completely, 1.5-2 million people dropped.
2% of ~100million working people is ~2 million people. 2 million people dropped out of the middle class to the lower class. 2,000,000. Two-million individuals. Two commas. Not to mention their kids. Or their retired parent(s).
