Casual pilots are, too often "broke and unhappy" and the smart ones are soon gone. But the "obscene lottery" that airline recruiting has become keeps amny of them trying, even though they are angry and unhappy. You just need to read Prune to see that.
In today's climate, full time GA jobs are not common, even out bush. Most are paid by the hour. So happy GA pilots are not common. It seems that happy regional airline pilots are not common.
And this is now affecting regional airlines, and sneaking into the major airlines. There is not really a difference. Flying is flying, and ALL commercial flying including most Australian GA needs stable, reliable, well paid, happy pilots who work long and hard at making things better. You do not get this with temporary pilots, who are paid by the hour (sometimes), or are paying to fly.
I believe we have already paid a very high price in human lives for not treating small aeroplanes as seriously as we should.
This is where the respect for GA pilots MUST start.
