Richard Florida’s new book, “The Great Reset: How New Ways of Living and Working Drive Post-Crash Prosperity.” equates the current moment to the nation’s two earlier major economic meltdowns — the Long Depression that followed the Panic of 1873 and the Great Depression of the 1930s. The reset that followed each of those episodes transformed the American geography in ways that fit perfectly into the new model for prosperity. It’ll happen again this time, says Florida, but it won’t be quick and easy.
