Nurses, who every day care for the casualties of the economic crisis driven by Wall Street greed, plan to hold a rally in Dewey Square at the site of the Occupy Boston Protest, to show their support for the movement and to highlight the MNA/NNU’s “Main Street Contract†campaign for a tax on Wall Street financial speculation to provide revenue for Main Street reforms, including jobs at living wages, quality education, guaranteed health care for all, and freedom from hunger, homelessness, and retirement insecurity.
