American immigration policy: a 75 year plan

Over the next 75 years or so, barring catastrophe, the global human population is expected to rise to around 10 billion before plateauing for a while and then, perhaps, declining through the first half of the next century.

Simultaneously, the developed world will face a demographic challenge as more people age out of the workforce than are aging into it.

If pretend that those 10 billion people will be distributed roughly evenly over 6 continents (N. America, S. America, Europe, Asia, Africa, Oceania) – they most certainly will not – then the US should be adopting an immigration policy that will target a population of about 1 billion people by 2100. Furthermore, immigration from Canada and countries to our South but North of Colombia doesn’t count because it is merely shuffling around the populations of the countries of North America that will, by out pretend rationalism, need to sum to about 1.66 billion. In fact, we should have open boarders with Canada and Mexico and freedom of movement and a common market with all the countries of North America, So the strategy has to be to permit overseas immigration of about 8.7 million people per year for the next 75 years. And really that means Africans and Asians.

Basically, if you are under 30, single, not a criminal, and are going to work, you should be admitted to the country, given a work visa, and put on the path to citizenship.

What does a strategy for inculcating a new New York City of Americans every year look like? What do our cities look like? How does our culture absorb them? What can we learn from them?
