What you're saying is nonsense. I don't even know who Steven Pinker is. Poverty two hundred years ago was way worse than poverty today in most of the world -- this is a self-evident fact to anyone with even a passing knowledge of history. No running water, no water mains, no sewers -- these things meant death from cholera and other diseases for many children, and that's just for starters.
Odd how you counter claims as fictional with zero evidence just speculation. I realize this is a discussion forum and not a policy office but I pisses me off when feelings is met with feelings and not explanation or examples. Now’s your chance to really prove your point.
That we're all less poor today that our ancestors 200 years ago is absolutely, totally self-evident. No additional evidence needed. Indeed, the inverse claim would require evidence, and extraordinary evidence at that.
