¿Cuándo pasó de moda el optimismo?

NEW YORK TIMES.- Though candidates on the right are full of fire and brimstone this year, the trend away from optimism is most pronounced among liberals. A century ago Progressives were the optimists, believing society could be improved, while conservatism saw the end-times approaching. Today progressive thought embraces Judgment Day, too. Climate change, inequality and racial tension are viewed not as the next round of problems to be solved, but as proof that the United States is horrible.

And yet developing the postindustrial economy — while addressing issues such as inequality, greenhouse emissions and the condition of public schools — will require optimism. Pessimists think in terms of rear-guard actions to turn back the clock. Optimists understand that where the nation has faults, it’s time to roll up our sleeves and get to work.

That’s why the lack of progressive optimism is so keenly felt. In recent decades, progressives drank too deeply of instant-doomsday claims. If their predictions had come true, today petroleum would be exhausted, huge numbers of major animal species would be extinct, crop failures would be causing mass starvation, developing-world poverty would be getting worse instead of declining fast. (In 1990, 37 percent of humanity lived in what the World Bank defines as extreme poverty; today it’s 10 percent.)

The lack of optimism in contemporary liberal and centrist thinking opens the door to Trump-style demagogy, since if the country really is going to hell, we do indeed need walls. And because optimism has lost its standing in American public opinion, past reforms — among them environmental protection, anti-discrimination initiatives, income security for seniors, auto and aviation safety, interconnected global economics, improved policing and yes, Obamacare — don’t get credit for the good they have accomplished.

In almost every case, reform has made America a better place, with fewer unintended consequences and lower transaction costs than expected. This is the strongest argument for the next round of reforms. The argument is better made in positive terms — which is why we need a revival of optimism.

Recently Warren Buffett said that because of the “negative drumbeat” of politics, “many Americans now believe their children will not live as well as they themselves do. That view is dead wrong: The babies being born in America today are the luckiest crop in history.” This was not Nebraska folk wisdom; rather, it’s sophisticated analysis. The optimistic view is that it’s still morning in America, and if we fix what’s wrong, the best is yet to come. Such can-do, better-future thinking needs to make an appearance in the 2016 presidential campaign. | Gregg Easterbrook
