Being born in a country is not grounds for citizenship in most of Europe. Jus Solis is only common in the Americas.

While I don't agree with a lot of the far right rhetoric, I can understand the reason why people are fed up with immigration. Skilled labor is mostly excluded from all the laws on immigration. The intended target of the policies are people of MENA origin. 40 years of mostly failures with integrating them into the work force and picking up the tab for them leaves a bad taste in the mouth.
