Setting aside the primary claim, I think there would be lots of secondary effects if this were taken to an extreme. Diversity is good in any system; in this case, exposure to people with different levels of income, different life priorities and personalities, different backgrounds, increases empathy and broaden's one's understanding of the world. This exposure is especially important in a large, democratic society. We've already started to see the loss of some of this cross-pollination in recent years, and the country's divides haven't been this deep in decades. Increased homogenization would be catastrophic, I think.
