Nobody picked up on it in my post on the Economics board, so I thought I would try it here.
For those who believe that all economic wealth is the product of human labor, then the more the people, the greater the wealth. Right?
Would 12 billion people make us twice as wealthy as we are now? Would 24 billion people make us four times as wealthy?
The usual objection to this line of argument is that earth is finite and we will run out of resources. That only makes sense, however, if resources are also a factor of production in addition to human labor. And if labor and resources are factors of production, can capital be far behind?
Anyway, I thought this might make an interesting discussion.
