I think in a few hundred years the very small number of survivors of humanity will be living in caves and huts in the high Arctic and in a greening slowly-reafforesting Antarctic, they'll be hunter-gatherers with maybe some simple small-scale unmechanised agriculture, and they won't have money. Maybe a barter system for a few.

Among the many other things they won't have is an economic model.

Europeans and Americans choose to make things unsustainable and unprofitable to do in Europe, and chose to make it possible to import things cheaply from places like China and India who use slave labour and destroy the environment … and then blame Capitalism.

As you like … but blaming capitalism is not going to bring industry back, and it won't stop China from using slave labour or India from using their rivers as landfills.
