Yet Keynesian economics has “perplexing durability,” probably because the theory tells politicians that their vice of profligacy is actually a virtue.
Jeff Jacoby explains why this is poisonous economic analysis.
Could anything be more absurd? The shattering losses caused by hurricanes, earthquakes, forest fires, and other calamities are grievous misfortunes that obviously leave society poorer. Vast sums of money may be spent afterward to repair and rebuild, but society will still be poorer from the damage caused by the storm or other disaster. Every dollar spent on cleanup and reconstruction is a dollar that could have been spent to enlarge the nation’s reservoir of material assets. Instead, it has to be spent replacing what was lost. …No, hurricanes are not good for the economy. Neither are floods, earthquakes, or massacres. When windows are shattered, all of humanity is left materially worse off. There is no financial “glint of silver lining.” To claim otherwise is delusional.
