Do you seriously think the quality of life wouldn't deteriorate rapidly if this was the case? Or is that not your concern? Or would it not effect your area, so you don't care?

I think it's utopian to believe that this would lead to anything but slums and shanty towns. People with no wealth will all flock to areas with wealth, which won't have the infrastructure to support them. They'd camp out wherever they could with whatever they could - possibly right outside your house. Probably in your back yard actually - local law enforcement would be too overwhelmed to go around persecuting squatting or trespassing.

Travel to a large city in India to see what happens when free movement is coupled with massive inequality.

It's certainly not ethically sound to lock out people from poor countries just because you don't want them to be poor nearby.

Under your model people would just end up building huge gated-communities anyway - it would all be private property, so wouldn't violate any of your laws.

People will find a way to keep people they don't want near by away from them.
