The real problem with this argument that is being made against the pilot academy graduates is that even if it's accurate to say that their skills, experience, and attitude toward the job are poor 99.9% of the time (which I don't believe it is), there are enough people who fit into this description who are not "250 TT wonders", as you say.
I went to Purdue because I walked out of high school knowing I wanted to be a pilot, only a pilot, and nothing but a pilot. It's what I've dreamt of since I was a little kid, and I saved money from working after school to take flight lessons as often as I could. Yes, my folks helped me to pay for the illustrious school, but so did Uncle Sam: I had a National Merit Scholarship and a Robert Byrd Scholarship, and then an NBAA scholarship among a few other smaller ones. This amount alone added up to nearly $15,000. I got several subsidized loans from the Stafford program as well, and so these loans were not accumulating interest while I was in school, and the Hope and Lifetime Learning Credit helped reduce my folk's and my tax burden from accumulated educational costs. I'm still claiming a tax deduction from my student loan interest.
I examined the idea of going the "traditional route", getting my ratings at a local FBO while earning a degree in something else, or not earning a degree at all. There were a variety of problems with that approach, I felt. First of all, none of my flight training would be eligible for scholarship or federal financial aid, and none of the tuition, fees, or loan interest would be tax deductable. That's a hefty pile of money right there. I also realized that immersing myself in aviation would lead to greater gains within the field, better networking opportunities, and a broader level of flight experience than just having a few thousand hours of dual given in my logbook. Why waste my time studying engineering, or history, or God only knows what else when I could be working toward a degree and flying at the same time? I thought about the possibility of losing my medical or becoming otherwise ineligible for flying and how "worthless" the degree could be, but I decided that the potential gains outweighed the risks.
And so I lived happily ever after graduating with 250 hours and jumped into the right seat of the RJ, right? Well, not exactly. I left Purdue with over 1200 hours, CFI-AIM, a BE400 type rating (which Purdue paid for), a bunch of simulator experience, and a lot of systems knowledge I doubt I could have gotten from the local FBO, or at least as easily. I didn't find myself in an RJ, though, as some nutheads decided to go and ram aircraft into buildings, so I ended up (after much job hunting) getting picked up by a freight operator flying checks Part 135. I did that for nearly a year. When I showed up at Chautauqua for class, I had nearly 2200 hours, 500 multi, almost 200 turbine, 100 hours of actual, 800 dual given, and several emergencies under my belt. Of the 14 in class with me, one had more flight experience. I'd flown all over the country, to large airports like O'Hare, San Francisco, and Cleveland, and lived in five states in a period of two years. I'd even observed flights to Russia and Europe while interning (and being paid very well to do so). I'd also had a pretty well rounded college experience, made a lot of friends, and had a heck of a good time. I got a Master CFI designation. I'm a glider pilot. I'm a published aviation writer.
Did I steal a job from more capable pilots simply because I'm from Purdue? No, not simply because, but in part. But so did many of the people in my class who were not from Purdue, ERAU, ComAir Academy, or any one of a variety of places where you can learn how to fly. And I know a lot of people with less flight experience than me who got hired before I did without any "bridge program" to help them out. Where's the angst for them? You can hold out hope that one day you'll just type numbers into a matrix and a computer will put you in class in descending order of "experience," but it won't happen. That's not how the game is played. There are a lot of factors that go into a hiring decision, and hours are only one of them. I made a great degree of effort to build the maximum portfolio of qualifications I could in the timeframe I did, and once you factored in my scholarships and financial aid, I think I did it more cheaply and efficiently than I could have any other way, though that may not have applied to other people in other circumstances. And though that doesn't entitle me to a job any more than anybody else, it doesn't any more mean I deserve to be here any less than anybody else.
So if there's any moral to the story, it's to disapprove of people like I do: without prejudice on an individual basis. There are a lot of pilots I've flown with that couldn't fly their way out of a shoe box, and they've come from every walk of life. Yes, some of them are from Purdue, but some of them are from some no-name flight school, and some of them are from the military. They have flight time numbers across the board.
