This title is nonsense .every country limits immigration .But this idea falls flat when you realize if the Aztec or Mayans tried to invade Apache or Comanche nations they would be met with overwhelming violence.and there would be no legal immigration. Just respect a countries laws.every country has borders that came about by war or treaty .as for the a.a.m racist comments about Europeans immigration policy.In Europe and U.S. is much more tolerant on immigration than say Africa or Asia.if you don't believe me research xenophobia violence in South Africa that happened last yr. Also Mexico has big as *** fence border with Guatemala.Now having said that I do believe there needs to be an increased legal immigration after a period of three yrs.
