Angus takes issue with this Hans Rosling video, which went viral a few weeks ago:
[P]eople, have you looked at the horizontal axis of his chart? The distance between $400 and $4000 is the same as the distance between $4000 and $40000. That is incredibly misleading. Properly plotted on a linear scale, it would be clear that there was way way way LESS income inequality in 1810 or that magic year of 1948 than there is in 2010. We are NOT living in an "age of convergence" with respect to per-capita incomes.
