It is difficult to raise incomes when the global pie is not getting any bigger and 200,000 additional people per day want a slice of it. We are well past the stage where this is sustainable, and are in the biological equivalent of an algae bloom sustained by non-renewable resources and fossil aquifers. This will end in ecological collapse if it is not done voluntarily and quite soon. The population numbers will come down until we are once again in balance at a fraction of our current numbers, but it won't be pretty to watch.
