The people doing the most damage to the world are billionaires who have access to power that the rest of us can hardly imagine, so we could talk about what it would look like to interrupt the cycle by not allowing them to reproduce and separating them from any existing children so over the long term other families have an opportunity to rise to the top (and maybe society would level out a bit in the process). If greed has a genetic component, this would also apply selective pressure against genes for greed.

What do you think OP, start with the billionaires?

Same about not teaching basics. When I was old enough to shave my dad gave me his old electric shaver and bought himself a new one. I get not giving a kid the nice, new thing, but it still felt crappy. And then he didn’t show me how to use it. So the first time I used it I rinsed it out with water. Turns out it wasn’t made to get wet, and it rusted horribly and was immediately ruined. All he had to do was show me once how to use and clean it and it would have lasted for years. This sort of thing happened over and over, I had to learn a lot of stuff the hard way because no one taught me.

Cool
