(The same airlines that argue -- correctly --- that they are subsidizing
GA).


Huh??? If that's true, lets reduce some costs NOW. First, get rid of
class A airspace. We don't need that, just make it class E all the way
up; two controllers for the entire U.S. should cover it. Get rid of
class B and class C airports. Close some and make others class D
(getting rid of a dozen approach controllers each). Next, shorten all
runways to 6,000 feet or less and sell off the extra land. Reduce the
number of parking spots (land cost) of all airports to no more than 100
spaces and sell off land. Gee, we can take most of the cost out and we
won't even feel it!! You can pretty much fire all clearance delivery
and ground controllers as well. We could get along just fine without
them too we don't have enough IFR traffic that we couldn't just use
tower to issue clearances.
