Two things, first the link to the msn is about how blues are wealthier than red states. It does not mention the ten most rich people. So this does not aide your argument, but thank you for at least suppling a soucre.
Secondly, why does your link to the New Americanist not link to them, but rather far rightwing propaganda sights. I tried search the New Americanist site, but found nothing on this subject, but it is an interesting site.
