Hm, I noticed the snarky thought "I can't come up with any large scale positive development[1] that I would attribute to redistribution".
But now I'm like "that's too snarky, you might just ask people for examples".
E.g. I'd attribute rising lifespan with improved nutrition (core cycle in the economy improving).
