We need DREAM but also H-1 visas, however I don't think they produce the same results. Most of us are children of immigrants so we are drawn to the sciences and while we would fulfill some of the need for H-1 visa, we aren't enough.

Microsoft wants engineering talent and as much as it pains me to say this most real talent is foreign educated (primary and undergrad). They come here for grad school. Bill is a huge supporter of revamping the America's educational system so we can compete but until then we would rather have the best and brightest working for an American company than a foreign one so we stay competitive.

I know someone who works for Microsoft, he started on an H-1 type visa there. He isn't a slave or underpaid. It's hard to argue he is being exploited and underpaid when he pulls in 6 figures. Microsoft actually follows through with greencards for ther H-1 workers.

I know Microsoft doesn't require citizenship for some of their scholarships and gladly gives them to DREAMers. Bill gates just wants the best of the best, regardless of immigration status. He'll support DREAM (I'm pretty sure he will) but let's not act like DREAM is enough to fix the problem he is trying to address. Let's not say we don't need H-1s and DREAM will do if we want his support. DREAM by itself is not nearly enough.
