NYC Charter Schools Like Silicon Valley?

Here is an excerpt from today's Wall Street Journal (22Sep2009), in an article titled "Charter Schools Pass Key Test in Study":

"We want to make New York City the Silicon Valley of charter schools," says schools Chancellor Joel Klein, who supports lifting statewide caps. "This study shows that when districts aren't antagonistic to charter schools, and instead welcome them, the results are very powerful."

Like Silicon Valley? With 12% unemployment? Massive traffic problems? Unaffordable housing?
I suppose Klein meant "innnovation" -- that he wants the charter schools to be innovative. It is a strange simile, though. Perhaps Klein could set his aspirations higher.
