Wow I am amazed. A professional pilot would actually say no to someone because of the way they gained their training, without regard to how well they fly or the applicant's ability to make decisions in the cockpit. Seems less than "professional" to me.
If you think about it there is a reason these guys are willing to put up the money to have a chance at a low paying job. There is a long term economic incentive to do it. Just look at the paytables for legacy or large cargo carriers, that is big bucks, especially to a young person. As someone else said pay the money to reduce the amount of time to get hired, be it a year or two and make a meager living instead of making a meager living for a year or two then get hired at another job at minial pay and be two years behind . Although you might not see it this way that is an indicator that there is at least a chance to make the big money. You dont see that kind of attitude for civil servants, factory workers or other honorable but less paying jobs.
Seems to me that many want a guarantee that they will always have a great paying job. As a wise person once told me if you want that kind of guarantee then get a good education that allows you to be independent of others. Be a doctor or lawyer, or another such profession that as long as you are ethical and competant you will always have a job, be it for others or for yourself. Quit being bitter about the decision you made in life. Flying is a unique way to earn a living but it, and you, aint that special.
