And what is it with everyone using the word "greed"? Greed is when you go to the pot luck at Thanksgiving and take all of the macaroni and cheese before anyone else gets any. What does it have to do with somebody trying to make money off of an investment. Selfishness (greed) has nothing to do with why somebody would make a risky gamble. If you are making a risky gamble with somebody else's money, that is greed. Using your own can be stupid, unwise, risky, crazy, whatever. You are using greed wrong.
Before lecturing others I find it's often a good idea to check if I'm right.
"Greed (Latin, avaritia), also known as avarice, cupidity, or covetousness, is the inordinate desire to possess wealth, goods, or objects of abstract value with the intention to keep it for one's self, far beyond the dictates of basic survival and comfort. It is applied to a markedly high desire for and pursuit of wealth, status, and power."
https://en.wikipedia.org/wiki/GreedSo everyone human being that drives a "new" car is greedy? Anyone that has a TV bigger than 32" is greedy? Any woman that gets a manicure is greedy? Those things are certainly beyond basic survival and comfort. I certainly have no desire for status or power. The only desire I have for "wealth" is just to be able to retire some day in an average sized home and not have to rely on my government or anybody else to take care of me or my family. Does that make me greedy?
