recognize no national boundaries
Answers
Answer:
What if there were no national borders?
We should all know our limitations. But what we could easily do without is the concept of national borders—at least as far as they limit the mobility of people. This idea may seem like a naïve utopia. But mobility without borders is already a reality, the European Union being a prime example.
Just imagine what a huge economic potential this could unleash on a global scale. Economists estimate that world GDP could be increased substantially—possibly even doubled—this way. The effect would be much greater than any gains from the free movement of goods and capital. Poverty could be combated on a truly global level for the first time. That would be a bold program for social equity.
What we are currently seeing is too little—not too much—international mobility. The common fear that the "rich" countries are threatened by massive inflows of migrants is completely unfounded. The actual migration potential under free movement is grossly overestimated
