In his inaugural address, Mayor de Blasio described social inequality as a “quiet crisis” on a par with the other urban cataclysms of the city’s last half-century, from fiscal collapse to crime waves to terrorist attacks, and said income disparity was a struggle no less urgent to confront.
“We are called to put an end to economic and social inequalities that threaten to unravel the city we love,” he said to about 5,000 people at the ceremony, many beneath blankets on a numbingly cold day.
Mr. de Blasio, 52, the first liberal to lead City Hall in two decades, delivered his critiques as his predecessor, Michael R. Bloomberg, whose Wall Street pedigree and business-first approach to governance seemed to embody the city’s current gilded era, sat unsmiling a few feet away.
It was only one of many potent symbols of change that dominated a ceremony unlike many before it.
