This is the correct reason. Putting aside the attrocious US education system the economy literally relies on immigration of both skilled and unskilled labour. They irony is some of the nation's most dependent on immigration (US/Australia) are the most vehemently against it, either because or causing racism. (chicken or egg I'm not sure). I can guarantee you no matter which populist you vote in their cabinet will not allow them to do any serious harm to immigration, noone wants to be the next Japan.
