The data in the economist article is for both forklift drivers and pickers. It seems fairly clear that even lower skilled warehouse workers are being paid less than they were before Amazon entered their market. The fact that automation is both reducing the number and quality of jobs probably merits discussion as well. We simply don't have anything in place to ensure automation doesn't ruin people's standard of living.
