IO540 I agree with your sentiments, but it is very difficult to raise the capital required for a new fleet. Banks and most investors run a mile when aviation is mentioned. Many GA companies are backed up by deep pockets and as such turn a very minimal profit (if any!).
Whirly, with all respect, you don't know what you are talking about. Try teaching people for a year earning a pittance, through all conditions and in horrible a/c. Then see how jaded you become.
I consider myself fairly dedicated, but there is no way I would go back to full time teaching again. It simply is not worth it.
Heli instruction is a very different job, the pay is vastly better and you generally do fewer flights per day, so are able to try and do a 'proper' job rather than rushing around like a headless chicken.
