If anyone knows the net profit margin of a US/CA/SA/Aus operator, I think that would be interesting.
I know of a very reputable fixed-wing and helicopter operator who just about break even each year; last year their net profit margin was half% - so it's not the operator being greedy or being a rip-off. The issue lies with costs including overheads.
However, the revenue disclosed by the operator does not include taxes (of any kind) since these are passed onto the government from the end-user (the customer).
Less demand will mean fewer operators and fewer benefits from economies of scale.
