I'm not really talking about just handing out more money to schools, nor debating whether schools received less funding. The school problem comes from both not valuing education and people who have had a rougher go at life that the problem keeps perpetuating in their children. (dad in jail, mom on drugs, mom working 2 jobs so has no time and the children just hang with other older children, etc.). Feel free to send your kid to that school if you think it's just as fair a shot at life.
Those sound like problems with the pupils, not the school. This is not semantics - it affects how to solve the problem, and informs what consequences various solutions may have.
