Chamber of Commerce and illegal immigration

I always figured the US Chamber of Commerce's push for illegals was due to money. By that I mean that they wanted to both hire people more cheaply and also have more people to buy their goods.

Mark Krikorian, National Review's resident immigration expert, has a different take that I found interesting:

Obviously, the supporters of amnesty and loose borders and high immigration levels think (mistakenly, in my opinion) that it's good for the economy. But very few of the most vocal actors are driven mainly by those concerns. Even Tom Donohue, head of the U.S. Chamber of Commerce, is driven by a quasi-religious fervor for open immigration, in my experience with him, something that actually harms the strictly economic interests of those who pay his salary. For instance, after a presentation he and I, and a few others, took part in, I had lunch with the chairman of one of the nation's largest corporations, who asked rhetorically something to the effect of "Does amnesty and the rest really matter to us? [meaning the other Fortune 100 CEOs and chairmen at the event] We pay way above minimum wage and don't have many illegal aliens working for us." He's right of course, but they like Donohue, he's done a good job for them generally, so they defer to his crusade for amnesty and open borders, including hiring MALDEF's former national policy analyst as the Chamber's director of immigration policy.
