Sorry, the world has no need for the bottom 90%.

The only thing which is important is that 95% of the world’s wealth is owned by less than 2% of the whole population, and the 1% owns more than 70% of the world.

If your IQ is not in the top 90%, better try to be good at soccer or singing. That’s the only way to propagate your genes in this world.

The world is going to enter Type I civ soon, but without most of the ‘extra mouth’.
