Every air force in the world is run by fighter pilots. Even well-meaning serious-minded people tend to emphasize what they know best. Hence air superiority tends to get far more attention than any other aspect of air combat operations.
Frankly, I think the US might be better off allowing the US Army to set up its own units for close air support. I suspect if they were allowed free choice of equipment they would operate some type of rugged STOL fixed-wing airplanes for that purpose.
