> The #1 problem leading to humans not having enough to live comfortably is that we have an enormous number of humans and limited resources.

It really isn't. The raw materials in our lives are a tiny fraction of our living costs in the west. 200 tons of concrete, steel, and plastic etc. in appropriate proportions is enough for a very nice house, yet it would cost less than a tenth of the sale price of that house: what you need to turn it into a nice house is expensive human labour.

The raw materials are cheap because we have machines to help extract them; before we invented them, those materials were also expensive.
