I have no doubt you have more experience at being a greater fool than most.
Is this greater fool theory based on buying something with the intent to sell at a profit someday?
Not everyone buys collectibles, art and a home with the intent to sell or make a profit. So I don't know how you can say anyone that buys that stuff fits in with the greater fools theory.
From my understanding, going on the basic idea of the greater fools theory, AP would not really fit well with that theory. I guess there could be some aspects of AP that might.
What if I use 2 match plays on baccarat while betting banker and player at the same time? Can you honestly apply the greater fools theory to that situation?
