that he'll willing to pay people more than required (by the laws of the land and by the laws of economics). Their minimum wage at Amazon is $15/hr (more than twice the federal min wage). Certainly he could find enough talent to work in his warehouses for less than $15/hr???
This is just one example. Many companies have similar policies. JP Chase pays a minimum of $16.50 now. (and they pay more than that in large cities).
The trend of companies paying more for labor is just starting and I think this letter helps other CEO's raise wages in their companies without fear of losing their jobs. I think this move will help with our income inequality issues. I hope CEOs take real action moving forward.
