I actually disagree with that assessment. I don't have the numbers offhand (I'm at work), but IIRC, we are actually paying more than our share through the taxes, if you use accurate percentages of use.
If you use the airline's insane 60% number (they claim GA uses something like 60% of the aviation infrastructure), then we are horribly underpaying our share, and we are, in fact, subsidized.
If you use a more realistic number - AOPA's number had us near 10% IIRC, we are paying more than our share currently.
If you use something in between, say 20% or 25%, we're probably pretty close to breaking even.
My question is what is the definition of "infrastructure" being used? I'm guessing each one is using different definitions, and there's where the confusion comes in.
AOPA is probably looking at the number of commercial flights talking to ATC in a day, or maybe even number of hours spent talking. In that case, commercial is going to be, hands down, higher than GA.
The airlines are probably looking at the number of airports that have commercial operations vs. the number of airports that are strictly GA. In that case, GA is going to be, hands down, higher than commercial. We have many airports available to us that commercial pilots don't use.
GA costs others virtually nothing so long as we are only VFR, stay out of towered airports, and the airports we land at don't require public funds in order to keep open. For a certain number of us that may be the case, but a lot of us fly IFR (or get flight following), land at towered airports, and those airports are public owned and receive public funding to keep their doors open. I can honestly see both arguments and I have no idea whether we're subsidized or subsidizing others.
A fuel tax would be fair (and the way I'd like them to go), but a 152 takes up just as much bandwidth from ATC as a Navajo or a 747, both of which burn exponentially more fuel. So, I can see the argument from the airlines for user fees that may tax us more.
The only way to reduce cost is to reduce liability, which is something that is long overdue anyway, IMHO.
Now that is absolutely correct. When you look at how much most of the purchase price of aviation commodities goes to liability, it's pretty insane. If the liability insurance wasn't so expensive, prices would go down significantly, and this stuff would become a lot more affordable for all.
Theo only was to both reduce cost and increase numbers would be to make it easier to get a certificate. Most pilots are too "elite" to allow this to happen.
We're shooting ourselves in the foot, unfortunately.
I'm having trouble with the word "easier" you use. I don't believe that we should relax the standards for the certificates and ratings we currently have in place (although the Sport Pilot license is a good example of fewer requirements with more restrictions). I do believe we should make it more affordable and accessible for people to become pilots. In that regard, we absolutely need to try to make it easier. It comes down to affordable and accessible. I know that I, for one, would not have bothered were it not for the particular situation I had that allowed me to do my training (cheap, good planes). I've not come across pilots who are elitist and want to restrict flying only to them. Really, everyone I meet is encouraging and wants to see more people learning how to fly. The local pilot's group has a mission that includes to help make it more feasible for others to learn to fly, especially the younger crowd. Get more kids flying means that you'll get more people who grow into it and participate.
Light Sport aircraft are, to me, excellent at helping make it more affordable for people to learn to fly. Experimentals are excellent at making it more affordable for people to buy planes that are still new and have capabilities wel past what certified aircraft in the same price range would be.
It comes down to we need to get more people flying and get more people to think positively of GA. I think we all try to do it in our own way.
