Assuming the problem is that the global energy consumption is too large, the last thing we want is to increase the energy footprint of the people we already have. Moving people from poor countries to rich countries means greatly increasing those people energy footprint. It is in direct contradiction to the stated goal of reducing the energy footprint of humanity, and serves as a strongly visible signal that the ruling class is not serious about reducing global emissions.
poor = small energy footprint
rich = large energy footprint
