In the near term, people increasingly not being able to afford basic necessities like housing and food will lead to increased societal violence, but that likely won't cause collapse.
Climate scientists are increasingly warning of ecological collapse, meaning core climate systems will fail, like the Atlantic Gulfstream which will cause global famine and destruction, and that might be the end of human civilization all together, we won't know until we do it within the next half century, and see the full extent of our fine work, a climate hostile to agriculture, dependable fresh water, possibly even standing structures not made of steel and concrete.
But man are we speeding towards that cliff for short-term private shareholder profit, wheeeee!
I'm on your side, and believe society should assist its people from those most in need. I'm a democratic socialist, and would be open to communism if automated resource gathering like robotic agriculture became sufficiently of age.
That said, the Nordic models are the easiest sell to eventually get there, as there is hard data that they are the happiest societies on Earth reliably by a mile.
If you can't sell the the idea that the point of a society is to maximize the wellbeing of its citizens, and the Nordic countries objectively do it best of all existing models going by the data, then there is just no reasoning our way out of our own self-imposed extinction.
There really isn't a more powerful argument I've encountered with concrete data to get others to realize that "the free market" isn't their friend and regulation and taxation is if you're a regular member of a society that doesn't have aspirations of global economic conquest.
You want to be happy? You want your neighbors to also be happy? You want your kids to be happy? You don't like living around tons of miserable homeless people and want them to be happy and housed rather than dying in front of your apartment complex? Nordic model let's fucking go.
