Terribly myopic and worrying world view. People who are scared that immigrants will take their jobs don't stop to think that these are jobs they wouldn't want to do, and jobs that complement theirs so their company can keep running and employing them.
Just my 2 cents worth: I'm convinced that the decrease in global population will lead to western countries doing a 180 and start competing to attract immigrants. Well within our live times. Seeing as machines don't pay into pensions.
