I am a CFI and I don't run into too many people wouldn't want to be a pilot...it is just too expensive for 99.9% of the population. 12k just to get the license and I am quick to tell them that a PPL is just a license to spend more money. Even if you could build a new J for 500K, you'd need to feed and maintain it. Not to mention that your weekends away usually run atleast $1000 a pop. So if you want to get away 10 times a year (otherwise why own an airplane), you are looking at 10k minimum in travel after you spend the half a million and probably another 15-20k a year to own the plane...it just isn't tenable for most people (myself included at this point).
