The horrendous images beamed around the world from Charlottesville, Virginia, serve as a poignant reminder that white-supremacist populism is a toxic force in the United States. President Donald Trump's repugnant response, coming out on the wrong side of history on both Nazis and the Ku Klux Klan, inflamed passions and reminded everyone that he is unfit to be president.

The Brexit vote, Trump's election and French President Emmanuel Macron's thumping victory are symptomatic of the age of anger we live in. Populism is about claiming to represent the "real people" and targeting the establishment, corruption and immorality. Populists feed on social discontent and promise to clean up a bankrupt system that is rigged for the favored few while the interests of the "real people" are neglected. They invoke culture wars and promise to revive and protect traditional values and community ties that have been sundered by a self-seeking elite. They promise a better life and trade in disappointment and nationalist grandstanding.

Populists have astutely exploited unease about job security and rising inequality, stoking resentment against the broken promises of globalization made by the political and business establishment.
