Bean counters and investors sit behind desks, they are not real jobs!!!!
Mate you need to get out of your cosy office and see the real world, your view of what goes on sounds very distorted.
Tourism is but a small part of the GA industry. Aviation up here revolves around our indigenous brothers and support for them. (contractors, electricians, builders, and government workers and the like)
If you are expecting to turn up in a suit and have mum dad and the kids boarding your aircraft wanting you to fly them to a five star resort you are way off the mark, more likely to be loading your aircraft full of frieght at 0600 in 100% humidty and heading off into the wet season to a aboriginal community in a rather smelly OLD aircraft, and learning a bit in the process.
Its government money that keeps aviation going and that is unlikely to change. The airline industry is different story, but sounds like that’s a few years off for you.
