Experts imposing their will on communities that later turns out to be wrong

If there is one lesson from the 20th century worth learning, it is that an exclusive focus on the defense of liberal fundamentals against a supposed totalitarian peril often exacerbates the social and international conflicts it seeks to resolve. This approach to politics threatens to widen the already yawning gulf between liberal groups and their opponents, while distracting from the deeply rooted forces that have been fueling right-wing populist politics, notably economic inequalities and status resentments.

The above comes from Moyn and Priestland's editorial today in the Sunday New York Times which I best explain as the tyranny of experts imposing a will on individuals and communities which over time has proven to be mistaken. For an example of a nonpartisan health issue let's use the sugar lobby funding research that labels fat as bad suggesting that it's intake in the diet should be reduced with fat free, oh by the way many made from sugar, alternatives. Our government's experts, The Food and Drug Administration, then go out and promote low fat diets and create an obesity epidemic.  Oops, now sugar is the culprit, and the FDA the dummy who had a hand in shortening and ruining thousands of lives. Get the picture about experts? They aren't. It's the same in foreign policy and finance.
