Sigh. What does or does not happen overseas is largely irrelevant to the discussion at hand. It could be that way but you'd need to fund and resource it accordingly. And you probably think flying is already expensive enough.....
Lots of aircraft mean smaller sectors, means more controllers. Less traffic means bigger sectors means fewer controllers. Lower density but similar workload.
I'm sorry, but the flying school is not operating in isolation out in the sticks where there are minimal other users. They are operating in close proximity to a major aerodrome and if the can't be bothered finding out that sort of information and try to help themselves to work within the system then they'll likely continue to get shafted.
You'd see even less when it's busy because you wouldn't be allowed anywhere near a console to avoid distractions. At least when it's quiet you usually get a chance for a reasonably close look.
