There really isn't enough work for all of us, so what do we do to fix that?
Without work there isn't enough money for everyone either.
At the time of the black death it was approximately the same situation. After one half of the population of the world died there was more work than people and the industrial age began.
Is it possible that a similar outcome is at hand. As the population of the world outgrows its available work and the conditions deteriorate to the point of unhealthy will a plague surface to destroy half of the population?
