Yes. There is much wisdom in your post. In the 70's there was frantic activity in GA, and the big manufactureres were bringing out new models almost every year. It was exciting with all that developement. Everyone imagined all kinds of things. The big companies were suggesting that soon almost everyone would have an aeroplane,and would be flying around the country for holidays. The oil and mineral boom started and tax incentives came. Everyone with a tax bill bought an aeroplane. Most could not fly them, but the flying schools were promoting and making money too.(buy one and we'll teach you to fly it.) Most Aeroplane sales companies had a flying school.
The sales companies had the latest models for demonstrators, and put them to work doing cheap charter. They had their own maintenance, got the spares under warranty, and did minimal maintenance (well it's new mate-nothing wrong with this one), and did not worry about depreciation as they sold it soon.
That's where the sub-economic charter originated from. And they kept telling us how cheap it was to run them.
Finally the bottom fell out of it. Sales slowed, and the tax concessions were not there like they used to be. The manufacturers blamed insurance costs, but I think they had just saturated the market. Australia had lots of aeroplanes and not much activity. And lots of pilots.
