I'm inclined to agree, we need a timeout & an assessment of what kind of country we want in the future & what sort of immigration policy would support that vision.
Won't ever happen, though. I was house hunting this weekend - the majority of the people I bumped into when touring homes were obvious newcomers, heavily accented, wearing traditional garb, etc.
The same scene is repeated in virtually all segments of the economy, I'm sure. There's just too much money being made by the few in a position to benefit to change things.
