I agree, wouldn't it be great to pay good wages to make instructing an better choice for career instructors.
(I certainly would not complain)
Any responsibly operated GA school is battling small margins already. How do they afford to pay instructors an attractive wage without putting the costs up for students?
Where would the money come from otherwise? Look at what the hourly dual rate is for ab-initio traing these days at a responsibly operated school. It makes me wince. The operators of these schools are not screwing their customers, they would be financially better off running a newsagency than a flying school.
I have no answers to that conundrum. Other than in civil aviation it has always been like this (even in the olden days when things like airmanship and flying standards were better)
And on that golden age and as far as the loss of airmanship and poorer training standards these days I admit I have made lamentations about this in recent times (and probably will again) however when I recall many of the articles in the old ASD Digests from that golden age when pilots exhibited high standards of airmanship and hand skills... I start to wonder how much actually has changed...
