The obvious response, which I thought of as soon as I saw this, is indeed contained in multiplereply tweets:
How about bank teller employment divided by total population size?
Ok but USA population went up +20% from 1990 to 2010 so tellers per capita did decrease over this period.
(McKenzie did not reply to either of these, for some reason.)
If you don’t normalize for population, graphs and claims like this are profoundly misleading. (Similarly to normalizing geographic data for population density, correcting for inflation, etc.)
