We have plenty of everything what we need for decades and longer. What we see is different in my opinion. The result - was that it in your question - is the same, but the cause is different. If I overlook roughly: - a lot of people - a lot of people. That lot of people can be separated into rich and poor (1-bit reduction). There are far more poor people than rich. The poor ones build clusters of different sizes. Usually the location of the many clusters is somewhat "in the neighbourhood" and so, one is able to identify bigger k-clusters In different parts of the world. The biggest clusters are also within the same k-cluster or, somehow, side-by-side. The k-clusters can only occupy the area which hasn't been occupied by the rich's clusters upfront. The area occupied by the richs upfront is usually good land what enables the rich to live prosper and develop, while the poors struggle for a living. This leads to tensions. Tensions lead to conflicts. Conflicts lead to refugees. Refugees lead to fears & jealousy and xenophobia. That amplifies everything and the loop starts. Economy and wealth is depending on resources. Like ones that can be sold and/or used, like oil, food, knowledge.. At certain point there must happen a pivot in the relationship between the poor and the rich, where the rich can not get anything useful from the poor anymore, and instead, the poor need rich's resources, so they're importing it. To keep up with the development speed of the rich, the poor need to get even more of the rich.. The rich need that for the economy of theirs. The loop closes after the last: While all that happens, the poors need an assurance for the elderly theirs, which is kids. No money, mo' kids. That amplifies EVERYTHING. So, the problem is the economy by itself, not the lack of resources bringing it to a halt, in my eyes
