Sure, take that stricter immigration control. But if people assume upfront that immigrants are intrinsically the source of problems and it takes stricter and stricter controls to filter them down to only those that bring value, this strengthening of filtering will never end.
Remember that one does not _either_ bring value or cause problems. I expect a typical human being to bring some value and cause some problems at the same time. And you can never measure which one is bigger.
