Some of the nation’s most important companies did not exist a generation ago, and many of the most important – Amazon.com, Google, Apple, Costco, Home Depot, Microsoft, FedEx – did not exist 50 years ago, The New York Times reports. The federal government has also been transformed over the last century, with the creation of Social Security, Medicare, the Securities and Exchange Commission, the modern Federal Reserve and dozens of other agencies and programs. The roster of major American universities, on the other hand, is largely unchanged. … One problem that stems from the relatively unchanged nature of higher education is its geography. The country looks very different from the way it did 100 years ago, but the distribution of our leading universities still has 19th-century echoes.
