All starts with welfare. If people were coming to find freedom and safety I would agree but most came because they can get free money and a treatment that is not even given to the citizens in poverty. That upsets people. While it's ok to help, it's not ok to refuse assistance to your people to help others that probably would have never helped you. We should thank for this horrible situation all those politicized NGO's that brought people for a purpose and that purpose was not to help them. Now the honest good people are paying the price.

Ending welfare and the handling of people who are living here illegally are two separate things. You're making it a binary issue. It's possible to do both things. And I haven't seen convincing data to support what you're saying.
