Suggestions about how Canada could improve really ought to be directed to the Canadians. They might be amenable to different policies in sparsely populated regions like Hudson Bay. Continental USA has no analogous areas.
Non-Americans who wish to complain about USA have a broad range of topics from which to choose; there's really no need to complain that USA regulates the operation of airlines in USA airspace.
I only commented on what is the current dynamic. Your thoughts on why there ought to be a different dynamic is interesting, but it doesn't seem like something anyone could predict.
