There is no US money because there is no value to US investors. The regulatory environment is poison. The industry itself has become backwards in part because of it. The customer base hates most anything new, while exalting the old and proven deadly, and is vocal about it. Most the money in aviation is made by regulators, insurance and tort lawyers. I’d include the lobbyists, but I’m not sure AOPA is still bringing in the big bucks.
The Chinese find value because they are even farther behind and they also see opportunities for evil doing.
It’s perhaps unachievable, but being a real success would likely involve complete vertical integration where your customer comes to your airfield, your school, and rents then buys, your planes. At least you need to approach that goal.
