At a guess... - Paying $15/hour guarantees a steady supply of replacements for people quitting. Paying closer to minimum wage does not. - At the scale and level of service demand of Amazon, it's probably better to have predictable headcount and per-employee performance than to try and play the fast food game where finding replacements might take weeks and even when you do, there's a good chance they'll be rather bad employees. - It's probably a self-selection filter at this point. Pretty much everyone knows that working for a fulfillment center or DSP will be a shitty grind, but the pay is better than 90% of other unskilled jobs. People who can't handle the work will largely self-select out of even trying to work there in the first place, which saves Amazon a lot of time and cost.
