There was a thread here along these lines some weeks ago. The issue is actually pretty evident to any non-aviation businessperson who stumbles upon an airfield. The business badly needs to attract customers who have real money.
But GA is stuffed with traditionalists - from taildragger and antique type owners on farm strips all the way to the top at the GA Dept of the CAA. Just look at the fight which gets put up over GPS. Have you tried to mention GPS at one of those CAA safety evenings, and seen the emotions expressed in the (mostly 60+) audience? You can get GPS fitted in a much cheaper car than an M3.
And GPS usage is just a very small beginning of the modernisation which is badly needed. What you are really looking at is new modern planes - serious money.
