Not a single nation on this planet is populated with people whose ancestors were "ALLOWED" there. What a specious, whiny topic.
Really?
So you are saying countries all throughout the world don't have an immigration process where they allow some people and not allow others?
So you think countries like China, Japan, Russia, England, Britain, Germany, Israel, the United States, etc. don't have an immigration policy, where people wishing to be legal immigrants to these countries have to go through?
You do know that countries that have had lax immigration controls on people coming into their countries like the US, Britain, France and Germany are now starting to have a large conversation about tightening their immigration standards, because they are starting to see their old lax immigration standards have prompted many people coming into their countries who are exploiting these countries at the expense of the taxpayers of these countries.
