There are a lot of Rush Limbaugh-trained "conservatives" here who are members of the "I've got mine" school. Its likely these people have never dealt with any kind of adversity whatsoever. Their thinking will change when either their own job is outsourced or some Chinese company undercuts their business.
Yes, they graduated from the Limbaugh Institute for Advanced Conservative Studies! They are much smarter than the XVIII century hillbillies.
Or, they are not conservatives at all in the traditional sense. Some are actually transnational progressives. They are the GOP's own version of the Thomas L. Friedman faction on the Left. I think you'll find that the origin of their beliefs is actually in the ideas of 1940s liberal utopianism. We let anyone into the tent these days. Maybe we need a purge.
