The article discusses the average, it'd be interesting to see the median given income does not have a normal distribution. It feels likely that aggressive behavior would create a higher variance, so more top earners, but also more people in severe debts or dieing earlier. I wonder if the latter has been corrected for, else survivorship bias may play a role. Also seems likely this would be correlated with wealth. Wealthy playground bullies earning even more than their wealthy non-bully peers, poor ones doing even worse than their peers.
