The human soul has three fatal weaknesses: money, sex and power. They all inflate our egos and prop up our insecure, fallen selves.
Of these, the one Jesus taught most about in the Bible was money. The fear of losing it (or of not winning it) is what drives most traders out there. As the OP pointed out, you have to die to yourself in order to overcome these things. (This is not the same as being born again, but it has a lot in common).
