"...The problem with this line of thinking is that low educational attainment is strongly correlated (and causally related) to low family income levels..." To be fair... The point of the article is that, in a lot of places across the US, low educational attainment is correlated with ALL family income levels. And the problem is how do you handle a situation like that? Put another way... even if the poor could get their kids into the top schools via vouchers or what have you... chances are, they would still not get as good an education as their international counterparts. Now there are some states, mostly in the North East and Midwest that buck that trend. But for everyone else... the test results aren't all that stellar regardless of income (or rather, familial level of educational attainment).
