Some subscribers to MathEdCC might be interested in a recent discussion-list post "Re: Growing Inequalities - Response To 'Haim'. " The abstract reads:

*************************************************
ABSTRACT: In response to my post "Re: Growing Inequalities" at <http://bit.ly/JVmTOi>, Math-Teach's Haim responded at <http://bit.ly/KSpXrz> and seemed to suggest that: (1) immigrants from Latin America are responsible for a significant fraction of poverty in the United States, and (2) income inequality can be reduced by restricting Latino immigration.
I quote excerpts regarding poverty among: (a) foreign-born Latino families, from Timothy Noah's book "The Great Divergence" <http://amzn.to/KLw98C>; and (b) Hispanic children, from the U.S. Census Bureau <http://1.usa.gov/KGCpet>, that, I think, cast doubt on "Haim's" suggestions.

"For the short term, preparing teachers in mathematics and science is a wise and useful step toward improving schools. . . . . .[But]. . . As quickly as possible, we must understand the link between poverty and educational outcomes in the US, devise solutions, and test and implement them. Britain briefly tried to substitute public relations for aircraft safety and paid with the loss of its commercial aviation sector. I hope the United States can avoid a similar error, that proponents of teacher quality and charter schools will recognize the weakness of the evidence before it is too late, that we will not damage public education, let down our most vulnerable students, and lose technical leadership we take for granted."
