Nothing new there. Liberals have always used working-class and poor public school students are subjects for their social experiments.
Their attempt to "desegregate" Boston public schools led to white flight. Those that could afford private and parochial school tution, pulled thier children out of public schools. When Cardinal Medeirous closed Boston parocial school enrollment, middle class whites moved to the suburbs, or sent their children to live with a relative in the suburbs. Though Howie Long is from Charlestown (Boston), MA, his family sent him to live with a relative in a suburb, Walpole, MA, to avoid Boston's Froced Busing.
Federal Judge Wendell Arthur Garrity Jr., who lived in the rich suburb of Lincoln, MA, saw fit to use poor and working-class Boston Public Schools students as guinea pigs for Forced Busing. Yet, that same judge did not inflict the same social experiment on nearby rich, white suburbs - like Newton, Brookline, Cambridge, Weston, Wellesley, etc.
What was good the goose was not good for the gander.
Those who forget the lessons of history are doomed to repeat it.
