Having more children a status symbol for more affluent?

Well, that's silly. Having more kids, i.e. DNA copies, is the end goal of signalling status. If we could imagine how displaying status this way could garner more resources per child, or possibly attract yet another mate, then we would have a theory.
The blogger is confident that longer term, there will be no population crash since there will only be children happy people left passing on their children happy genes.
