I agree with you. The countries really at risk are the third world countries. Like Mexico, Central & South American countries, Islamic countries and the like. Inshah Allah.
I've read that the Black Plague in Europe resulted in a rise in demand of workers & that wages went up, living standards went up and survivors actually benefited.
That took about three-four generations though. I wouldn't want to be the ones that had to live through the interregnum (assuming one lived through it) to see the benefits on the other side..
