Not necessarily, we whites may only continue to exist up in the north where our light skin is an advantage and not a liability. Whites in tropical areas with much sun at all are statistically not going to last, skin cancer will weed them out. But, up in the north, skin needs to let in all the sun possible to make vit. D.
Given vit. D enriched milk in the cartons won't be available in the supermarkets etc in the future after a crash, folks like Mexicans may not last long term up in the norther regions. But then given a choice, who'd want to? When there are nice warmer places to live?
If you're in an area destined to be part of the Reconquista and want to stay, might as well work on fitting in now, learn your Spanish, marry a gal they call Senora and not ma'am, and more power to you!
If there's not a total collapse, the writings of Steve Sailor (
www.isteve.com) are interesting, he's studied countries in south america and various demographic trends quite a bit, he thinks the US is headed towards a white ruling class that lives in fortresslike compounds and a brown peon class, based on trends he sees in the US and how other countries have developed in s. america. Sounds like one miserable way to live for everyone concerned.
