Let's do some math for fun. Amazon now employs about a million workers in the US. Let's naively assume 3/4 of them work in warehouses and delivery as opposed to corporate. Let's also assume they work, on average, 2000 hours a year (roughly full-time). For Amazon to raise those wages by $1/hr (or lower efficiency demands by ~7%) it would cost them around $1.5B every year.

Now, you're probably thinking that's chump change compared to Amazon's profits, but fun fact: Amazon's online sales segment doesn't make much profit. In fact, it lost $200M in Q4 [1]. So you basically want Amazon to either go deeply in the red, or else they have to raise prices on products to also raise worker wages.
