It's interesting because I spoke with a former student, now instructor. He owns a Cessna 172 restart and was telling me how he has been making money with it on leaseback. The numbers he told me would lead me to believe him.
AOPA has been trying to do a lot to stem the tide of GA pilot losses. I think looking at "best practices" in promoting flying clubs isn't calling out a death sentence for the FBO. It is geographically driven.
