They need to improve the training quality in my opinion. Is someone who has flown a C172 around a Texas farm for 1500 hours more valuable than a 500 hour pilot with deep understanding of jet transport flying/sim training, etc? Not in my opinion, I feel if you want to become an airline/jet transport pilot, then you need to begin that learning process from the beginning to understand the dynamic operating environment it takes to be safe and successful in this industry. It's been working in Europe for years, and I think it's time the US adapts a similar process. It's not just about how much experience you have, but the quality of your experience that makes the difference. KLM, Lufthansa, British are good examples.
But with that, if airlines want qualified pilots, they need to pay for it! The only reason the airlines don't want the 1500 hour rule is money, they know they will have to raise their poverty salaries which cuts into managements fancy bonuses!
