Not sure about this, here in London I don't think people support Saudi sheikhs, despite being generally pro-immigration (possibly in contrast to the rest of the UK). Although you're right that almost no politician would oppose immigration of wealth(y). Edit: Although I do agree that there might be an effect similar to this, I think it was also present in Slovenia versus other Yugoslavian people. I wonder how much it has to do with the perception of wealth directly, and feeling threatened by "inferior" culture - there's probably a correlation, in addition a poor society is percieved as more likely to immigrate in larger numbers.
