We are supposed to feel sorry that the new regulations may affect the bottom line of the “union” workers who do not perform any actual work for the money they make. Horses do all of the work on Central Park South. They are bred into an existence devoid of any natural contact with other horses. Forced to stand for up to 9 to 14 hours a day, in all manner of weather, in dangerous midtown traffic — these horses never get to enjoy the park that they encircle. And in the end, according to the Daily News, they end up in a glue factory for all of the abuse they suffer. No wonder so many of them have tried to escape. No wonder they keep collapsing from exhaustion. Eddie Sullivan
