When a guy can afford to donate his salary to charity, you know he's loaded. Arriola, Miami's blue-eyed angel of death -- er, city manager -- made off with a cool $42 million when he sold Avanti/Case-Hoyt, his family's printing business, two years ago. Since then he's done a magnificent job of flaunting his wealth. First he joined Merrett Stierheim's team trying to straighten out the public-school system (salary: one dollar), then quit in a huff, but not before insulting Stierheim by calling him a "horrible leader" who "doesn't respect women, or blacks, or Hispanics." More recently Arriola publicly insulted the reform-minded chairman of the county's Public Health Trust, attorney Michael Kosnitzky, labeling him a "cancer" in that organization. Then he accepted Miami Mayor Manny Diaz's offer to become city manager and loudly proclaimed he'd donate his six-figure salary to the United Way, but not before unceremoniously, gleefully, firing several veteran city officials. Is this what it means to be filthy rich?
