As much as I like Boortz, and as much as I agree with his opinion, this statement is way off base. I haven't priced small airplanes in a long time, and I quit flying in 1984 because of the expense, but I seriously doubt you could get into a small plane (other than kits or ultra-lights) for less than $100K. You should be able to get into a nice bass boat for under $40K.
If his statement was true I would own a plane and be flying it every weekend. As a pilot he should know better.
You can get a complete rig for about $22K at Bass Pro Shop.
You’re correct. I got out of private aviation in ‘90 because paying $30+ an hour for a 152 just didn’t make sense on my budget. I believe most new small airplanes (4 seaters max) run well over $100K.
