I certainly don't understand the context of the email or the people involved, but that seems extraordinarily douchey. Perhaps I'm the exception, but when your primary focus is on being a multi-millionare, you are missing something from your life.
I don't think that's the main focus of the post - its more about sticking to commitments and making stuff happen in spite of obstacles. Obviously money is a financial reward but that's not what I picked from the post.
