Got a minute? I wanna tell you a story.
There's a pit- in France, I think- that's a trove of Neanderthal bones. The presumption is they'd toss the bodies of their dead down into it; males, females, young, it's like a long-term mass grave. One of the skeletons was a grown man who'd suffered terrible injuries- one arm was amputated below the elbow, a wrecked hip, lower jaw screwed up, bad stuff. Thing is, all those injuries had healed well before he died. See what that means? The tribe or clan or whatever had nurtured this individual- fed him, helped him move with them, kept him safe and warm. They had no surplus, lived hand-to-mouth, but found a way to care for one of their own.
Any reason why a wealthy modern society shouldn't care for it's sick and injured?
