Why, then, doesn't he send them to public school? Well, the obvious reason is because public schools in Venice are full of Hispanics and blacks (one of them is 95 percent Non-Asian Minority), and, privately, Guggenheim doesn't think his kids will get as good an education in a classroom that has to cater to NAM needs. But, no way no how is he ever going to say that in public. He'd never get another Oscar.
So, Guggenheim makes a well-publicized documentary to blame his private decision on what's best for his kids on the horrible, evil teachers unions who prevent America from Closing the Gap. See, if only the teachers unions weren't screwing up black and Hispanic students so bad, Davis Guggenheim and his wife, movie star Elizabeth Shue, would be happy to put their kids in a 95 percent NAM school! But until America decides to Fix the Schools and Close the Gap by firing bad teachers, they'll just have to continue to drive past all those public schools to their private school.
