On the Uses of Savings

I am going to use most of my life savings to buy an airplane since it is the fiscally conservative thing to do.
I can hear the sharp intake of breath, see the snap of the spine to full extension as though electrocuted, and hear the indignant cries of "Rape!" "He's spending his money on an Airplane!"
Money is just one component of wealth. Durable goods of investment grade are also wealth. The power-house financial companies like General Electric have long understood this and quite often the engines on the airliner you fly on are not owned by the airline, but leased from GE.
Liquidity is the issue. If you want perfect liquidity, put only cash in a mattress. No growth, no fun, great liquidity!
The reason I'm buying an airplane now is a studied reaction to my observations during this pilot training evolution. My fellow students are men and women of some means spending time and money to learn to fly after 60. Or returning to flying, but opting out of all the commercial-inspired requirements of the Private Pilot route.
Currently there are not enough flight instructors and schools to match demand and it will get worse as word of this Sport Pilot license and it no-medical policy spreads. As the license numbers increase the demand for Light Sport Aircraft will increase. I expect to be able to recoup every dime I invest and make a profit on the sale of my plane. That's why I'm buying an old man's plane. Big cabin, fast climb and designed to cruise in comfort.
Just changing wealth from one form to another. And using the aircraft in the interim.
