There is alot of merit to this premise, and I've heard it alot. I think this is applicable, but not always in aviation.

Somebody whom is low time and gets a freight job, flying single pilot IFR in all weather, including low imc precision and non-precision approaches is a whole lot more qualified than somebody whom is a CFI with 2,000 hours dual given of which almost all of it is day vfr doing touch and goes and stalls.

I think CFI'ing is repetitive, mind numbing, dangerous, and incredibly boring all at the same time.
