There's really nothing new about hostility to immigrants in the United States. The last generation's wave of newcomers is the next generation's "old guard", saying that the new wave is "lazy", "unskilled", and a leech on society. What's going on today seems like a fairly straightforward continuation of how we've always been.

There've always been lots of people who would say that the next wave of immigrants is unneeded, and unwanted. No matter how successful they turned out to be.
