edit: If you're downvoting at least comment with why you think this isn't the case
There is a saying that the FARs are written in blood, as in regulations aren't passed willy-nilly, but passed after there has been a serious incident.
Air traffic is one place where "Iterate quickly and break shit" doesn't work. What happens when in the name of "efficiency", one tower reduces current safety limits because "99% of the time these are unnecessary", then the one time it actually was necessary, you've got two jets about to make a head-on collision, or one quickly changes course, loses control, and crash-lands into a town.
There are absolutely improvments that can be made with the FAA, but privatizing ATC is definitely not one of them.
I see what you're saying, but couldn't these same regulations be applied to private industry?
You don't necessarily need 0 governmental oversight for it to be private.
(I'm not saying that privatization alone has no potential or that it is not necessary; I merely question whether it is sufficient.)
That's both insane and inane. There's a simple incentive to improve aviation safety that has nothing to do with capitalist competition: people don't want to die in plane crashes. Airlines, otoh, would be happy to be able to cut corners and save billions at the slight cost of a few dozen more customer fatalities per year. Putting Airline is control of ATC by proxy will ensure the latter outcome.
