and they become less poor afterwards. Eventually, they will no longer accept the low wages as their own wealth increases. i think this is a good outcome - all parties benefit from the transaction.
This will take a long time to play out, and in the mean time, the research and development of tech would progress enough to find a solution to the energy and resource problem - increasing efficiency, or finding new sources to extract (my money is on asteroids).
But the way it will play out, means that there's always a gradient of relative "conditions" - from the lowest, to the highest. As long as this gradient is always shifting up - aka, everyone's condition is improving - i think it is acceptable.
