Do yourself a favor and look here.....
US Civil Airmen Statistics
There is just as many pilots today as in 2002. Actually there are more student pilots than 10 years ago. Same for flight instructors. Little less ATP's but that is going to change when next years statistics are coming out.
There is no pilot shortage. There will never be a pilot shortage. There will only be a shortage of people willing to work for poverty wages when they can have a 9-5 job and stay at home with their families. When the pay increases to the level of responsibility and when management compensates us for the sacrifices we make living out of a suitcase, all seats will be filled. It's that simple.
