Actually on your first point, that’s why society is devolving. All the stupid people that would have logf since joined the choir invisible are nannystate coddled and remain in the gene pool. The result is that as they breed, the stupid passes down another generation.
The natural order is thus disrupted.
Not to worry.
The human race has not changed ONE iota since the beginning of the human race. We are NOT any better, nor worse, any nicer, nor meaner, any smarter, nor more stupid. Exactly the same.
What IS different is that there are SO many more of us. In 1800 there were 1 billion people on the planet. Now there are, what, six billion plus?
So it SEEMS that the natural order is disrupted because of SO MANY more folks around. More people DOES equal MORE idiots. There are more smarter folks around but somehow they don't SCREAM out at me like the stupids do.
Abraham Lincoln once said that folks' behavior can be modified to some extent but human nature cannot be changed. I guess he would know.
