I think as a species we ran into problems when we developed such an amount of compassion that we ignored survival of the fittest as far as intellect.
As our brain developed, we could afford to have members who were not as fit physically. Hell, I was blessed with poor eyesight, and if glasses, contacts, corrective surgury hadn't been invented through our intelligence, I'd have been dead long ago, crossing the street or walking off the edge of something.
Not to say you must have intelligence above a certain level, but everyone should have something to offer. Some people have more brains, others have more brawn, some have both.
Now we have lots of people that, in the darwinian sense, are useless both physically and mentally.
But they are tolerated, and are given the excuse of "they made poor choices", or "they haven't been educated about that" i.e. getting pregnant when it was unwanted.
I really get tired of that "made poor choices" ****. Some people **** up, knowing they can use that excuse, and there is some sort of safety net they can fall into.
I say take away the safety net for a while, and let's see how fast more people start to make excellent choices.
What do I think of humans? I think humans tolerate far too much poor performance. Not to say everyone needs to be an alpha plus. I mean in that people who are a delta minus are given the tasks suitable to a gamma plus, and everyone has to live with, and come to expect, and accept, the meager results. I think many humans will take sloppy shortcuts if they think no one is looking, and that is bringing us down as a whole.
Hey, I'm no alpha, but but don't try to pretend I'm capable of, or deserving of that work. I am the absolute best epsilon minus I can be.
