This is actually a really good argument for not tying wages to company success. The baseline wage for Amazon employees should simply be the cost that it takes to house and feed them which is entirely different from the value they produce.
No the baseline wage is what the market will bear. Employment is subjected to market forces just like the goods and services those employees produce. The common example is underwater welders: high demand, low supply (high danger factor) results in $300k/yr salary. Welders at the local muffler shop in my area pay around $20/hr, highly skilled welders get between $75-$100/hr depending on if their independent or work for a large shop, and experience.
