The Texas 10 has its good and bad points, ma'am. I personally don't think it's all that ... but, like AA, it's better than nothing, I guess!
The biggest problem with it is that while it gives many more Black children the opportunity for higher education, because the State is broke (mostly due to government-initiated reforms) tuition to these schools is still out of reach for many, many African American and poor families, and Bush's policies are making it harder to get student loans and making less money available.
So ... you make it harder to get a child out of high school (No Child Left Behind) ... you make it easier for them to get accepted into college (Texas 10th).... then make it impossible for them to be able to pay for it!!
I don't believe it's a plan ready yet to be implemented nationally, but the basic premise of it, I think, is generally a good idea.
And, no, I think Affirmative Action (appropriately implemented) would be a much more effective idea.
