The aspect I want to call out is his matching of complexity, IQ, and jobs. He presents data on the levels of IQ representative of each profession. From the job types, this is clearly Canadian data, and perhaps dated but it broadly aligns with similar data sets I have seen in the past based on more contemporary US job categories.
People in these professions are in the 85th - 96th percentile of cognitive ability (IQ of 116-130):Peterson makes the claim that jobs for people with an IQ of less than 85 are very, very rare. I do not know about the validity of that but of course there is some point on the continuum it must be true. But Peterson makes the equally critical point that 15% of the population has an IQ of less than 85. Basically, there will always be people whose capabilities are less than the minimum required for functioning in a modern economy. What do we do about that?

We have not had good answers to that unasked question to date, a fact that is exacerbated by past policies of open-borders (increasing the competition for those at the lowest end of the capability pyramid), then exacerbated by global trade, and now exacerbated by automation. Especially automation.
As I said, I knew all these constituent facts but Peterson forces a stark question which makes much clearer how important is the issue. It also highlights just how inconsequential are most of our political discussions (and really, almost more importantly, our non-discussions) around these topics.
