I agree completely. Management usually requires different training than actually doing the job of the managed workers. That's why my niece with the expensive edumacation went right from college into a management trainee program.

I got a BS in biology and ended up writing software. Did I need the Biology degree? Not really, but then I always declined offers to join management. And there was a lot of synergy between the college work and what I was doing in medical research at the time.
