Anyway, your initial premise is wrong - according to wikipedia at least:
Navy: "over 4,000 operational aircraft."
Air Force: "The United States Air Force has roughly over 7,500 Aircraft commissioned as of 2004"
And of course, the Air Force does more then just fly planes. There is also Space Command - ie. satellites, launch vehicles and such. And of course the missile forces.
I was AF for 8 years, and loved it. We did all sorts of jobs, and just because you're in the AF, doesn't mean that you're in the air....I've been an instructor, a technician (radio comm and electronics), supervisor, grunt, seen the dirt, the air...you name it.
The current array of service options keeps things in check I believe, as not everyone that enlists/serves is cut out specifically for any specific service. I almost went Marine, and during testing for both Marines and AF it was determined that the AF would give me the best immediate exposure to communications/electronics at the time.
The separation exists in the history of the US Services, back in the Army/Air Force days, IIRC. But it's worked out, so no need for the gvmt to change anything...
