And why not? AOPA is VERY imperfect, but there is no other organization working to keep it possible to go fly a Cub or 152 around without European-style regulation and costs.
I couldn't possibly care less about flying a 152 when management has been able to cut pilot pay so much that most pilots can't afford the GA hobby in the first place. Once we get pilot pay back to 1977 level wages, corrected for inflation, maybe then I'll give two sh--- about GA.
