That's badly stated. Average = median (sorta(*)), above, not mean. Or: some people's consumption is so low that their life sucks. To change that, we don't need everyone to consume more ("rising tide lifts all boats") but just those people.
(*) I say sorta, because to complete my argument, I need to discuss the impact of human population, but that brings out the Malthus name- calling!
