So, this person apparently thinks that the way to keep the economy healthy is for the population to keep growing without limit. I fail to see why an unsustainable population bubble should be any better than an unsustainable housing / tech-stocks / tulip / South Sea bubble.

Such predictions have been commonplace for a long time and their track record is not very good.)
