unfortunately, humans as a species are adversed to change and scared of "the new and different"
also, while the human species main drive to compete and fight for existence is to breed, that world will never exist, even if there ae other ways. the urge to procreate is just to strong. at least, this is what the science tells us.
but things are better. by and large, the kids these days are better by leaps and bounds than they were when i was at school rather than teaching in one, and while that may only be in the soft and affluent South (of England, our South is very different from the American South), it's still better.
