I very much am growing towards the opinion that the "next one" (which I stand by my previous name of Great Annihilation for) is going to be the death knell and exceed all those that have come before. Reasons to believe this:
1. The rate of profit continues to decrease and make capitalism cycle faster, which will translate to worse average crashes.
2. The cushion of wealth held by working people in the countries directing global commerce and has not returned, that money has been claimed by the ruling class and now funds their useless finance games instead. The majority of the population in the US at least cannot survive a serious economic strike, even short-term.
3. There is a real world outside the useless finance games and the material conditions of the population have worsened considerably. Destitution and especially collapse into mental illness have spread like wildfire. There are more homeless people and beggars on the streets now than I've seen in a decade. Corps are playing things very close to the chest right now, and this increasingly cuts off the ability of workers to receive wages, as well as taking further from them by neglecting their "customers" when the industries in question are medical, housing, or transportation related. Precariousness related to car payments and loan payments has increased greatly, and this in turn increases precariousness for what remains to pay rent and power.
4. Extreme degradation of infrastructure combined with worsening climate conditions will harshly limit any recovery and increase the chances of reaching a crisis point.
I do not have a International Monetary Fund-approved study to prove any of this, but since "actual economists" just make all their shit up too I feel like we're on a working playing field. I am increasingly confident that the next hammer blow will shatter the workers, and their sharp remains will cut the ruling class. If there's another shell game to play this one off into, I sure as hell don't see it.
