A key fact is that economics does not take account of the ecological cost of producing more houses or cars. The amount of forestry and minerals required. The amount of CO2 generated, or the amount of land covered over with concrete, or the amount of oil deposited in the soil and water. Economics is the conversion of resources with the consequent entropy bill which has heretofore never been taken into account. GDP doesn't recognize its existence, only focusing on the plus side of the ledger, what products have been created and sold. What capitalism and GDP do not measure is all of the other things that add value to a society, like stay-at-home domestic work, one who grows their own food, or who engages in community sharing of talent and resources. Now that the ecosystem is no longer capable of producing what is required to maintain GDP growth, and as return on investment slows, the capitalist system is faltering.
There is also an increasing food supply shortage. To make matters worse, giant corps are buying up arable land in droves and do not grow food, instead using it as an investment for profit. Or some of that land is used to farm, but only with huge agribusiness tech and ships the food out, not creating local jobs or feeding the indigenous population. And frequently such land was taken from locals by governments to sell to the corps. Yet the locals are left with the pollution from such farming practices, and without jobs to buy their own food, thus exacerbating the food shortage problem. This goes double for the clean water shortage, caused in large part by huge agribusiness and high-tech manufacturing. Global corps are now trying to privatize this commons as well to control where what water is available to their production processes, not to thirsty human beings unless they can afford to pay. And so-called free trade agreements are supporting this privatization of natural resources.
