Eh. That video is slow, but i'm already somewhat familiar with Spengler.
I think basically any theory that gives an exact time limit for something is pretty much garbage. Or at least any theory that gives a time limit for social constructions.
It's silly to think any culture or way of life will live on indefinitely but to give it a post marked date and choose specific choices to make your point and group stuff together is somewhat silly in my opinion.
Current Western culture will be exceptionally hard to overturn because of something Spengler could not have forseen.
Mass free trade. Western culture is shipped everywhere and quite worryingly overwriting other cultures. pretty hard, making eastern europeons want to become rappers, Polynesian girls sensitive about their weight... and any number of other changes.
Sure some people speak out about it, but they seem few, and far from the majority of their countries... and even tend to embody some of the aspects they decry. Making many of them seem like the rich celebrity who lives in a house worth millions, spends more in a year then most countries GDP's and talks about the plight of the poor and how greedy the rich are.
Something they say just to feel better about themselves.
I think western dominated culture will last for quite some time, with any shifts happening within it's small confined boundaries... and a new system will only come about through a REALLY big disaster.
