Only one solution for failed inner city schools - school choice and competition. The poor children, many Blacks, have no way out unless they can escape from thee awful schools and get into non-union schools with discipline and order.
And who do you think MADE those schools "awful"? Mostly the black students, with their anti-education attitudes, cutting classes, disrupting classes, violence, threatening teachers, etc. They crap up their own neighborhood schools, then are bussed to better schools, which they promptly turn into garbage cans like they left behind.
