Since joining the New York Times as a columnist in 1999, Paul Krugman has emerged as a hero of sorts for the American left, and with good reason. He's been a dogged critic of George W. Bush's foreign and domestic policies and a fierce defender of the current administration's Affordable Care Act. His contempt for austerity and the hawks that champion it at home and abroad is palpable. But even the fiercest of progressives have their blind spots, and El Señor Krugman's happens to take the shape of my native Puerto Rico.
