Socialism works only as long as they have access to other people's money.
Similarly, economic globalism only works while there is a pool of cheap labor available, either to import or to outsource to. Just as socialism drains money from the middle class to pay for social programs for the indigent, globalism functions either by draining investment capital from developed countries and funneling them to the Third World, or by dumping the surplus population of the Third World into the developed world.
Consequently, globalism will collapse for the same reasons that Socialism has collapsed.
