I think you’re wrong. I think the bushes are globalists who envision an American Union not unlike the European Union. Being wealthy elitists, however, they won’t have to suffer the indignities that the rest of us will suffer. Mass shortages, declining property values, etc.
They aren’t mutually exclusive factors. The family situation only feeds into the “we’re all one big happy global family” illusion. Some of these globalist people really aren’t malevolent so much as disconnected from middle class realities and naive about the long-term consequences.
