I know, it is a serious concern here and in England and I suppose in Germany too.
Where I live we really haven't been affected by the illegals. I know people up here would start a revolt like you speak of in Az.
I wish I had an answer for it, moreover I wish a competent Politician would solve it.
That's what we elect them to do.
They suck up all the resources, its coming to a head now, so I think something will be done.
