Like it or not — and the mayor’s critics hate hearing this — Bill de Blasio has already made significant, measurable progress in supporting middle-class families and putting a dent in poverty. The administration recently pointed to numbers compiled by the federal Census Bureau showing that median household income in New York City has grown by $7,501 during the de Blasio years, from $56,298 a year in 2013 to $63,799 in 2018, which is a 13% increase.
