I read this earlier in the week, but had to take some time to think about the implications of this idea.
Now, the author may be on to something here, and I would think that this would suggest much more scientific research be done on the subject. If the road to wealth begins with a different mindset, or perhaps if we discovered that some people are, indeed, hard-wired to eventually become rich, we might have unlocked the secrets of true egalitarianism.
