Hm, interesting. Seems like a non sequiter. Knowing that alcoholics and junkies are a problem NOW, I'm for putting locks on liquor shops and pharmacies. That's more accurate.
Open borders means open borders, does it not? It means that you let anyone in, including those that will bring nothing but problems from those regions. Not controlling immigration is just begging to be colonized by people that don't share your values and will bring social ills to your doorstep.
That's great, but your projections about where the world will be in the near future are laughable if you think they will mean open borders won't cause the issues I stated above.
Africa has long had resources. I don't see that as a game changer. Or are you saying that when their resources are stripped, the colonization will stop and their problems with it? Are you one of the people that thinks everything wrong in the world is the fault of the West?
