Mexicans are the neo class slaves, and sanctuary cites are created for the benefit of the upper class that exploit them, not Americans. Real immigrants don't NEED sanctuary. Do they? Why don't we create a sanctuary for American poor? Well, it boggles the bloody mind, dosen't it?
The cost for real (honest/legal) immigrants to apply for entry into the united states is about $500, and they have to be on a waiting list, while being vetted to ensure that we are not getting actual criminals or terrorists. The process can take a long while. The illegal migrants cheat the system, basically thumbing their noses at those that follow the rules and as they don't go through the vetting process, they can be thieves, murderers, rapists and terrorists. Also, some of these so-called refugees from south-of-the-border, claim they have left their South American country for fear of their lives, yet once they crossed into a different nation along their border, they don't stop there, where the populace speaks their language and they are no longer in fear for their lives.
