Let's assume that you are correct. Don't schools in the states receive a large percentage of their funding from local real estate taxes, thus creating financial inequities between districts? One could look at that and view "financial inequities" as being a problem for schools to overcome, but you cannot. You see, because those taxes are paid for by the residents, that is taking money away from them in order to help fund the schools, thus removing money that would otherwise remain in the pockets of those residents making them richer. You might be correct in saying that poverty causes leaning problems, however because you have a situation where you really can't say whether the chicken or the egg came first (does poverty create learning problems or do learning problems create poverty?), there are far too many variables to say with any degree of certainty whether it is one way or the other. I will say that it seems fairly obvious to me that if there are learning problems, then that's going to lead to lower incomes. At least a lot more obvious than saying that learning problems are caused by lower incomes. At the end of the day, your idea is that the more you tax residents of lower income neighborhoods to pay for the education of their children, the more educational problems they will have. and no, I don't think the earth is flat. I saw a map once, so I know that it is a rectangle.
