ultimately it's only whites that can keep the globalized economy running, and without enough whites, it all falls apart. "not enough whites to keep global trade going" and "not enough whites to survive the collapse" are lightyears apart.  most of the nonwhites on the planet would starve to death in one generation without whites fueling global economics. not "a lot", most. every government would collapse.  you could reconquer that planet with 10,000 whites if you had to, most of it would be empty wastes.
