im getting back into finishing up a private pilot's license (there are a lot of requirements to be met), and im really more depressed now about GA than i was about 5 years ago when i did my initial training. it all got started about two weeks ago when i was visiting my parents in small town, mississippi, and had them drive me out to the local airport. it looked completely abandoned, wind sock torn to shreds, etc. apparently it isnt abandoned, but its obviously not used much. mississippi is FULL of airports like this ... MANY of the municipalities in the state constructed small airports after world war 2. there were very high hopes for aviation at the time, especially general aviation.
most of those airports are now abandoned and/or used by only a handful of enthusiasts. most of the aircraft in use are 1960's and 70's vintage which require constant maintenance. im sure this is no surprise to people who have been flying for awhile, but to someone just starting a pilot's license, its shocking. we dont drive around cars from the 60's and 70's, unless we are collectors.
anyway, what im getting to (and this is imo only, im not trying to step on any toes), is that i think that general aviation is being regulated out of existence. new aircraft cost as much or more than a house, and there is little incentive to create new designs because of the expense of the certification process. the cost and requirements of flight training are truly astronomical (and i think that both high cost and high requirements are directly related to over-regulation). as long as the cost is so high (and it will be as long as the requirements are so high), more and more people are going to be squeezed out of GA. add to this the rising cost of gas prices, and the picture becomes even more grim.
imo, the sport pilot license is a BIG step in the right direction ... but even it is ridiculous. in my mind, there is no reason on earth why the sport pilot license is enough to fly the new taildragger sport cub being developed by cubcrafters, but is insufficient to fly a tricycle-gear vfr cessna 150. besides, all of the minimum numbers aside, the only people who REALLY know whether you are ready to have a license, in ANY plane, are your instructor and the examiner.
btw ... i have no problem w/ faa regulation of commercial/ATP flight. but to me, GA is completely different. its your own time and your own money (your own freedom, essentially), the only people you put at risk are yourself and those who consent to fly with you. sure you could crash into people on the ground or whatever, but you could do that just as easily with a CAR

.
i think the only way that GA will survive is with a change in the laws, and especially a dramatic change in FAA regulation of GA. anyway, sorry for the huge rambling post
btw, i agree 100% w/ berk ... the best thing GA has going for it right now is the AOPA
