Adams will be remembered for his petty corruption, his self-mythologizing, and his ignominious dealmaking with the Trump White House; but he should also be remembered as the mayor who got New Yorkers to stop tossing giant bags of trash onto city sidewalks as if there were no alternative. You can laugh at a New York mayor who walks into a press conference wheeling out a trash can, beaming as if he invented the contraption, while “Empire State of Mind” blares triumphantly in the background. But truly, Adams’s proclaimed “trash revolution” represented a tremendous advance over abysmal past practice.
