Consider this post and stunning chart from Nick Schulz at AEI’s American blog recounting the prior private sector experience of Cabinet from every administration since Theodore Roosevelt’s.

As Schulz says:

When one considers that public sector employment has ranged since the
1950s at between 15 percent and 19 percent of the population, the
makeup of the current cabinet?over 90 percent of its prior experience
was in the public sector?is remarkable.
