Translation: helps kids not learn English and never integrate into society.
That's not what happens at all. The only Spanish kids in our school who can't speak English are the new immigrants. The rest can speak at least enough to carry on conversations, and a high proportion of them demonstrate proficency in the language and thereby are assimilated into the regular education tract.
If bilingual education is ended (which won't happen but hypothetically) the hispanics in America would become a permanent underclass in a few decades. Which probably doesn't bother people such as you and Gingrich and Hunter and Tancredo, but it bothers the rest of us.
There are several approaches on dealing with those school children whose language is not English.
The most effective is the one year immersion technique.
The other methods (which unfortunately predominate) don't really teach English, but merely handicap a child for life in the United States.
The ongoing (non-immersion) methods are a waste of money, ineffective in achieving the purported object, and often hijacked by those who are actually opposed to English proficiency.
So, the predominant form of bilingual education itself handicaps children and should be abolished.
