PARIS — From the all-powerful president with the infallible touch, Emmanuel Macron has become the “president of the rich,” an elitist dispensing fiscal goodies to the wealthy. At least that is what parliamentarians, some economists, television interviewers and newspapers have been calling him in recent weeks.

Barely six months into his presidency, Mr. Macron has been brought down from the heights to places many French are deeply suspicious of: the corporate suite and the banker’s office. Over and over that unflattering label — “president of the rich” — has been affixed to the young leader.

“You are committing violence with your policy. It’s you that are going after the poor to give to the rich!” thundered François Ruffin, a firebrand of the leftist France Unbowed party.

Mr. Macron was guilty of a “heavy moral, economic, and historical sin,” the best-selling economist Thomas Piketty wrote in the newspaper Le Monde.
