Basic income would become a part of the whole picture, for sure. But take Norway as an example: 5 million people and around a trillion dollars in sovereign wealth, which could yield ~ $8k per person (man, woman, and child) per year in perpetuity. All Norwegian citizens now own a share of ''Norway Inc'' as their birthright and receive a healthy dividend. Now 5 million people - that isn't a lot, and it's easy to imagine that over a generation, at least another 5 million immigrants would be interested in migrating. Now we're at 10 million people and our benefit is cut in half. If we're Norwegians, does the entitlement to basic income make us a little more defensive and nationalistic than we otherwise would be? It seems that, while many forces in Europe for decades have successfully pushed towards more open borders and more flexible immigration policies (ultimately spurring GDP growth), the transition to a basic income economy (if it occurs before the developing world catches up to the west) could act as a strong headwind in the other direction.
