> Eventually, the working population crashes because the portion of wealth allocated to them is not enough, followed by collapse of the elites due to the absence of labour. The inequalities we see today both within and between countries already point to such disparities. For example, the top 10% of global income earners are responsible for almost as much total greenhouse gas emissions as the bottom 90% combined. Similarly, about half the world’s population lives on less than $3 per day[0][1]
This is from 2017. This has gotten, in my view, much worse and is not continuing to alleviate itself, and I believe climate change is only making this worse over the next 5-10 years as wealthier nations and their wealthiest citizens try to insulate themselves further from its effects at the expense or perceived expense of the poor. I don’t think the current political climate is going to prove its sustainable.
Couple that with serious economic pressures as in part, a result of globalization and coming shortages and issues of natural resources and it’s a recipe for real disaster
