...only if it means moving to poorer place (this needs rent/buying property regulation). The other way you would end up with rich countries (read EU for instance) collapsing under flood of economic migrants unless they would completely scratch any welfare. We see where it goes with "refugees". There is reason why economic migration should be regulated, I have no problem welcoming economic migrants who upon arrival declares he won't use and won't be eligible to any welfare in next five years, but it would still cause problems anyway with people living in ghettoes willing to lube worth much lower living standard undercutting locals from low paid jobs.
