I hate it when pilots take jobs that build time only to leave when they get hired by a regional for less money and then leave to go to a major for less money again. It's the market and every pilot is chasing a dream that promises more money/bigger aircraft/away from home longer/self-satisfaction.

If you were a small GA business owner what would you do? Pay someone a higher rate to fly a single or twin who may or may not be a good employee? This same pilot will have serious Jet-ITIS as 99% of your qualified pilot will or do. Or have low expectations for them to be an average to good employee but great pilot and watch them hit the door in a few months. A high turnover rate of pilots for GA keeps labor low but lowers customer service and usually gives the business a higher insurance premium but a higer safety margin as pilots are not as complacent. GA is a tougher market than the Airlines when it comes to management and most pilots have no clue as they have Jet-itis and think they can do better.

Remember the Market sets pay rates. If someone will fly a 737 for 40/hour than a major airline will fill that seat. If someone will fly a 182 for 40/hour than a GA company will fill that seat. The catch is both pilots will never be happy staying in either seat at that rate for too long.
