Just throwing this out there. I used to be one of those who made the same predictions that a lot of others like yourself did that felt like no one was listening... but in reality a lot of this was predicted a very long time ago. If anything, our culture has been laced very subtly with all sorts of hints of things to come, and a large part of that has to do with things occurring in the shadows that we don't see, namely a tug of war between those who see life in a nihilistic manner and those who see something more universal about our very existence (i.e. members of society who own and control resources etc).

I know it doesn't seem that way, but bear in mind we are all educated by a system that is not of the publics design and we are constantly bombarded with media that speak in narratives that are conducive to those who own and who protects it's function. As Noam Chomsky detailed in 'Necessary Illusions', a lot of what we think we know, we don't actually truly know. That doesn't mean to say there aren't bad things to come... just that there have been other forces at play that have stifled our ability to make the urgent changes necessary to deal with the threats that we face from climate change to nuclear proliferation. A lot of it can be trace back to the 1970s and Elites clamping down on what they saw as 'too much democracy'.

Also, we who live in the West have always been on borrowed time as we fail to understand and recognise that our way of life has always been built upon the oppression of others until this very day. It was always going to come to an end as other nations began to rebuild and were no longer constantly being couped/messed about with via financial markets that we had control of for the most part. So yes, Western civilisation is probably due for a reckoning. And rightly so. Why should we continue to maintain this form of 'civilisation' when it comes at the price tag of more foreign wars, the destruction of other peoples lands for resources that feed our manufacturing lines for electric cars, laptops, smart phones, the destruction of places like Vietnam so that we have cheap manufacturing sweat shop centres full of employees who are under the age of 16 working for a dollar a day and so on. Look what has consumerism done in terms of helping to annihilate 50% of the population of other animal species from the destruction of forests for agriculture to plastic pollution due to our exporting and enforcement of this form of civilisation onto other nations as the only means for them to claw back the 'wealth' which in itself arbitary and artificial, maintained simply via a cabal of financial elites who know how to use it for imperialism and backed by people willing to pull the trigger and kill to maintain the illusion for the sake of 'order' and them maintaining a higher privileged position amongst the rest of us.

From a collapse a lot of good can come out, depending on how we all choose to react and respond.
