"There is nothing wrong with being a CFI or going to Jet U or GIA or getting a job towing a banner at the beach."

I think there is. You're comparing getting paid to do an honest entry level job to paying for a job that's part of a scheme to lower the career expectations of pilots. The idea being that an airline doesn't need to hire copilots if it can find people willing to PAY to be copilots. It's not a healthy thing for the profession....

If you think nobody is going to care during the course of your career that you went to Gulfstream, you're living in a bubble. I think that attitude is perpetuated at Gulfstream cause that's what you guys all want to hear. If you're not sure about that, do a little research here, at flightinfo, or at jetcareers, and see what you come up with.

"And call me a scab if you want but I'm enjoying what I'm doing and my quality of life is outstanding"

I don't think you're a scab but that's exactly what a scab would say. "I'm enjoying what I'm doing and life is outstanding". People that came before both of us sacrificed tremendously to make this career what it is. They weren't scabs and they didn't pay for jobs.

Believe me, many in this career don't, and won't, ever look highly upon someone who PFJed. Best you just keep it to yourself...
