Over the last generation the difference in incomes between people with a lot of formal schooling and those without it has risen a lot. Mickey Kaus had an interesting post about the subject the other day, pegged to the release of Senator Mike Lee’s new report on the decline in associations in America, and I wrote yesterday to make some amendments to Kaus’s argument. Also yesterday, Senator Tom Cotton (R., Ark.) echoed Kaus’s arguments nearly point for point at a hearing about the report.
Starting around the 1:18 mark here, Cotton brings attention to the same chart Kaus highlights, says that this wage divergence between educational groups might help to explain the decline in associations, and suggests that limiting low-skilled immigration could reduce that divergence. The points are valid, I think, but also overstated for the reasons I noted yesterday.
