I did downvote you because you said I could, but this is absolutely true. But, it kind of should be true. Government employees need to strongly know the industry they’re regulating to regulate effectively. I can’t imagine someone with zero financial ties and only knowledge from school going to direct how the SEC does investigations any more than I can imagine the same happening at the FDA.

I don’t think there should be so much regulatory capture (there is), but I do think a revolving door of sorts for many positions is helpful from a perspective of knowing the regulated industry and acting with the best knowledge of regulating that industry.
