NEW YORK — New York City's new mayor is marking Martin Luther King Jr. Day by talking about economic equality.

Mayor Bill de Blasio told a packed audience Monday at the Brooklyn Academy of Music that the "price of inequality has deepened." The mayor says economic inequality is closing doors for hard-working people in the city and around the country.

Citing King, De Blasio says, "We can't wait."

The mayor ran on a platform to battle the city's income inequality, which he dubbed "the tale of two cities."

He was joined by his wife, Chirlane McCray; New York's senators, Charles Schumer and Kirsten Gillibrand; and the newly elected Brooklyn borough president, Eric Adams

The event was dedicated to the late Nelson Mandela.
