"Working" for Gulfstream isn't training. It is a job. A flying job.

Here's a good example. When I was CFI'ing I wanted to live and work in FL. Gulfstream was an option. However it wasn't - because I would've had to fork over almost thirty thousand dollars if I wanted the "job". At what point in the job selection process should companies hire employees based on how much money they can pay for it?

On your point about how Gulfstream hasn't affected the airline world - keep in mind Mesa was doing 1900 routes down in FL - the same routes Gulfstream is doing now. Gulfstream kicked Mesa out of FL and displaced all of those people. Mesa isn't the pinnacle of places to work, but it's infinitely better than Gulfstream.
