For context: if Amazon were to use all of its profits from FY18 (~$11B) to pay its ~650K workers more, it would come out to just under $17,000 per worker.
Last year was neither a typical year nor is that the profit from retail.

AWS makes good money, but you can't really expect them to use it all to subsidize retail (even more than they already do) forever.
