> Are you saying that no company pays their employees enough?
Companies pay enough to get the quality and quantity of employees that they need. Those who are coming up short on either side are the companies who are (presumably) not paying their employees enough.
> Or that employees in general shouldn't be paid a living wage?
In general, my answer is "null" here, as the definition of living wage is continually (and it seems to me, intentionally) slippery/non-specific. Make some definitions that are stable over a long period of time and that labor advocates agree to, and only then can we have a conversation.
> Or even that Amazon, a company headed by the actual richest person in the world, really makes zero profit and must absolutely hurt customers in order to make ends meet?
Amazon does not hurt customers overall. I suspect you either meant to say employees, or perhaps have introduced a new argument that I'm not following.
With respect to profit, Amazon is now profitable on a GAAP, EBITDA, and cash flow from operations basis. I believe that was always the plan and it's coming together now.
Whether or not a company is profitable and whether or not the founder is the richest man in the world does not feedback into an employee pay issue in my opinion. A profitable company can afford to pay its employees for longer, but has no obligation (legally or ethically) to pay them more, IMO.
