Cities that are major or regional hubs will also thrive as they become the beneficiary of increased consolidation. Smaller cities heavy on particular aspects of the economy, for example those overly exposed to manufacturing or the FIRE economy (Finance, Insurance, and Real Estate) will need to adjust their economic model and demographics. Government and college towns will prosper because of their ability to attract and maintain members of the creative class. Two types of jobs are growing in size and salary: creative class jobs and routine service jobs. The geographic sorting of people based on ability and educational attainment is the highest ever. Cities with cosmopolitan bases such as Austin, Boston, and San Francisco are seeing large increases in population, with a heavy concentration of creative people. Former industrial cities such as Buffalo or Akron are falling behind by both measures. Consumption habits are changing drastically, particularly with the younger generation. Young people tend to have a negative perception of owning a car, and are less likely to purchase luxury goods. They are more likely to spend on experiences or social activities. Florida sees enormous potential for the mega region, a combination of major cities located close together. He lists several notable ones around the world including the BosWash corridor which encompasses Boston, New York City, Philadelphia, Baltimore, and Washington D.C., and ChiPitts which contains the major cities in the American Midwest. He argues that these mega regions are becoming spikier and are creating a disproportionate amount of productivity and wealth for the global economy. As the cities in these regions become more connected their dominance will increase. The suburb versus city debate will not produce a winner; the solution is a complex mixture of the two. They will both become part of mega regions, with many of the suburbs emerging into mix use communities. He cites the Northern Virginia suburbs of Washington DC as early examples of this. Big cities with a diverse demographic and creative base have proven that they are the most capable of attracting young people and new talented graduates. Cities like New York City, Chicago and San Francisco are where the most graduates flock each year. Florida argues that cities benefit from economies of scale and produce the most efficient systems for the economy, environment, and transportation. He sees this scale as an advantage as cities become smarter and more versatile. Florida has drawn criticism for taking an overly academic and elitist point of view. Critics argue that he overstates the size and potential impact of the creative class, neglecting many economic and social realities. They also argue that he ignores many factors that people consider when they are choosing a place to live.
