Do you really think the ruling class has any plans to allow that to happen... There's a reason so much surveillance tech is being rolled out across the world.

If the world needs 1/3 of the labor to sustain the ruling class's desires, they will try to reduce the amount of extra humans. I'm certain of this.

My guess is during this "2nd industrial revolution" they will make young men so poor through the alienation of their labor that they beg to fight in a war. In that process they will get young men (and women) to secure resources for the ruling class and purge themselves in the process.

In a simplified economic model though.
