"The places that are booming in size aren't the economic boomtowns — the regions with the greatest prosperity and highest productivity. In theory, we'd expect those metros, like the Bay Area, Boston and New York, to be rapidly expanding, as people move from regions with high unemployment and meager wages to those with high salaries and strong job markets. That we're not seeing such a pattern suggests that something is fundamentally amiss. The magnets aren't working."
