Glenn Reynolds points to an interesting article here about how successful Arabs are in the US. In fact, according to the article the average Arab in the US has an average income and education higher than the average American. It would be interesting to see them compared to the average Jew in the US, but I'm just not motivated enough to look it up right now.
It's interesting on its face, but I have to wonder if this isn't skewed by some huge outliers. After all, an Arab who can make it to the US was probably doing really well at home already.
