You clearly have not been in a classroom recently.  The teachers are mostly NOT bilingual and don't even get a bilingual aide unless the percentage of Spanish speaking students is over a certain percentage (north of 25%, I think).  Most teachers have to use bilingual students as interfaces to their students who don't speak English.  This is an arrangement that can benefit everyone if a teacher takes advantage of it and allows the language differences to enhance whatever is being taught.  It is the non-English speaking students who have problems getting extra help - not the English speaking students.  That is the reality in the classrooms - I suggest you pay a visit to your local public school before making broad assumptions.
