Theres a billion kids from Shenzen though. They could literally do all the work in America. Then theres 1.5 billion people in India on top of that.

I dont know what the solution is but this is the argument for the destruction of western civilization.
And maybe that would make a lot of people happy but I would not want to live in a world without things/ideas that Western civilization has created.
