The Storm After the Storm David Brooks puts an historical perspective on race and natural disasters.

Hurricanes come in two waves. First comes the rainstorm, and then comes what the historian John Barry calls the “human storm” – the recriminations, the political conflict and the battle over compensation. Floods wash away the surface of society, the settled way things have been done. They expose the underlying power structures, the injustices, the patterns of corruption and the unacknowledged inequalities. When you look back over the meteorological turbulence in this nation’s history, it’s striking how often political turbulence followed.

Then in 1927, the great Mississippi flood rumbled down upon New Orleans. As Barry writes in his account, “Rising Tide,” the disaster ripped the veil off the genteel, feudal relations between whites and blacks, and revealed the festering iniquities. Blacks were rounded up into work camps and held by armed guards. They were prevented from leaving as the waters rose. A steamer, the Capitol, played “Bye Bye Blackbird” as it sailed away. The racist violence that followed the floods helped persuade many blacks to move north.

Civic leaders intentionally flooded poor and middle-class areas to ease the water’s pressure on the city, and then reneged on promises to compensate those whose homes were destroyed. That helped fuel the populist anger that led to Huey Long’s success. Across the country people demanded that the federal government get involved in disaster relief, helping to set the stage for the New Deal. The local civic elite turned insular and reactionary, and New Orleans never really recovered its preflood vibrancy.
