Maybe it’s different in Mexico, but in South America they used gringo to refer to all white people from America to Europe to Australia.
And everywhere we went we kept seeing more and more answers to that question. These idiots think that if only they can steal California, Arizona, New Mexico, Texas, Nevada, Utah, Oregon, Washington, and (yes) British Columbia they'll be 'rich'. The truth is that they'll destroy the wealth of these territories the same as they have done in Mexico.
