It’s estimated that if we responsibly allocated all resources on the planet, it’s feasible to provide enough food, clothing, shelter, healthcare, and education to every person. It would be hard. But we just need to decide that this is the objective and stop equating the right to exist with greed.
It isn't that hard. The state of Kerala in India, with 36 million people and a relatively modest GDP, has achieved all of the above through its elected Left Front governments. There are richer states in India, but they are plagued with homelessness, dire poverty, and poor education. Worth a visit.
Great idea! I have a good friend whose parents are from Kerala. He goes every couple of years.
