The post-Big Dig era is coming for Haymarket’s pushcart vendors. It remains to be seen how they the pushcart vendors will fit into this new era, which will inevitably bring high-value real estate development and a broadening of the number of markets operating in Haymarket Square. The pushcart vendors understand that new competition and new construction threaten the way Haymarket has operated for a generation. Their efforts to forestall change have been counterproductive and wrongheaded. The future of the Haymarket pushcart market depends not on the outside protection the market vendors have sought, but on their willingness the willingness of the market vendors to embrace change that’s rushing toward them, whether they like it or not.
