I currently favor models that go after "easy exit, hard entry". Freedom of movement without standards causes problems. We should be free to go where we please, but it's up to other nations to set the price.

Within a nation, tiered citizen privileges with some sane defaults should control the degree of social security. Keep human rights intact, keep a basic standard of living intact, but ensure that all work is productive and that the people receiving welfare have a plan to not be economic deadweight.

I'm just one miller on the content farm: if there's one thing that I'm going to take away from this, it's that my ratiocinations don't mean jack shit. I'm still curious as to what other people think.
