I have no issue with skilled migration and this article and thread has not been about skilled migration but about the UN trying to 'force' a hate crime definition and in essentially open up all migration to be free from control.
Skilled migrants will migrate and generally add to the economy. Unskilled migrantion, simply moving for food/safety etc, could be more controlled by removing the root cause and help grow a standard of living in the point of departure.
Do you see mass migration between western european powers? No, you absolutely see some skilled migration and people pursuing some job opportunities but you do not see what you see from the third world as standards are broadly similar. This is what we should seek to promote and encourage as opposed to dealing with issues at the end point.
So you want to uplift 6 billion people from poverty? You realise that the more you share Wealth across the world the worse it gets for advanced economies right? Atleast until technology catches up to eliminate a lot of issues, there will always need to be a majority poor for our consurmist waste based society to merely exist.
That means there will be an infinitely increasing migration pattern, the root of the problem isn't as simple as making their lives better, we've pooped out a bit too much baby wise.
