Dont want a bunch of cartel and whoever to just walk over the border. Open borders is a big HELP for human traiffickers. Who move children into USA through our border. Many people are shipped there from Europe to be trained as sexs slaves and sold.
You cant have a welfare state AND open borders!
And that is why I do not advocate for a welfare state.
Do you plan on creating a culture that is not welcoming to people who pose a threat to your societies stability? I am sure you are well aware of the plights and instability of multicultural societies.
Diversity also makes group cohesion less possible because not all cultures have the same values and trust. How can a high trust society accept people form low-trust societies, only to be taken advantage of?
What do you think of Hans Herman Hoppe?
