No, believing otherwise is naive. Zuckerberg isn't lobbying for more H1Bs out of the goodness of his heart and a profound belief that labor arbitrage will make the world a better place. Labor is Silicon Valley's biggest expense, you had better bet they're trying to reduce that cost.
If we're going to allow foreign workers, they shouldn't be shackled to employers like H1B workers are.
