We have so much we could do to improve our world: build more infrastructure, repair and improve current everything, clean and maintain roads/parks/etc.
We have enough food, energy, and random consumer goods for everyone to have plenty.
I’m not sure exactly where the market failure(s) are, but they certainly exist. I suspect they are the product of it being far more profitable to play games with other people’s money (or just made up money, in the case of many large business loans) than it is to feed or clothe a thousand people.
I’m afraid we’re too entrenched to get out of this mess without a lot of bloodshed.
