There is a difference between recognizing the impact of race and class in America vs. using that impact as an excuse not to educate kids. We are not going to be taken seriously if we somehow get contorted into a position of arguing the being homeless and sleeping in a car doesn’t impact your readiness and/or your capacity to learn.
We cannot do what the protectors of the status quo do: begin with talking about poverty and end with talking about poverty. NO! We must begin with our unequivocal stance that poor children can accomplish great things in spite of the cards they have been dealt. But, to act as if we do not understand the difficulties of overcoming the odds of not having the level of resources that are needed to be productive participants in our society makes no sense. We must fight a two-pronged battle, but we can never cede the point some try to make: that we must eliminate poverty before we can have good schools. But nor can we be oblivious to the negative impact on our kids when they lack the minimal resources needed to prepare them to come to school.
Look, the entire premise of the "achievement gap" frame is that homeless kids sleeping in a car can achieve at the same level as middle and upper class kids. It doesn't take any contorting to see that.
