“Hierarchy is an unfashionable thing to defend or to praise. British government ministers denounce experts as out of tune with popular feeling; both Donald Trump and Bernie Sanders built platforms on attacking Washington elites; economists are blamed for not predicting the 2008 crash; and even the best established practice of medical experts, such as childhood vaccinations, are treated with resistance and disbelief. We live in a time when no distinction is drawn between justified and useful hierarchies on the one hand, and self-interested, exploitative elites on the other.”
