Two-way bilingual programs

The LA Times published an excellent program on two-way immersion programs: http://www.latimes.com/news/local/la-me-bilingual-20110508,0,3841220.story

Glendale has become the flagship city for two-way immersion programs. Kudos to the parents and administrators who are so invested in providing this type of education. Now, why is it that it is okay for middle class children to be bilingual, but it is not okay (by the state and the district) for working class kids to use their first language resources in the classroom? The message we are sending is: If you are a middle class kid, then we promote bilingualism; but if you come from a working class family, we want to erase your L1. What a wasted resource!
