Subjective morals aside, contrary to popular belief, you can't actually get very far in business while being an asshole about it. The only way to get far in the private sector is to give others something they want. You can be a total asshole and still get elected or make money in politics though (e.g. Gingrich, lobbyists, etc). As for being self centered, again, the only way you can make your own self centered life better is by trading something with someone else, be it your money, your skills, or your good/services. So even if you are narcissistic and self centered, at least you gave a lot of other people things to get that way.
You need to spend more time in business. It is called lying to your customers. There is much less competition in most industry and most are basically monopolies so either you pay ball or not. Also, you don't need to "get far", you just need to "get enough" and cash out and say "f**k em".
I am not going to waste my time with this line of discussion. I would rather continue elsewhere, no offense I hope but I just think you are not being objective enough on this subject.
