The only reason most companies pay a living wage is because they have to, to attract enough employees. Amazon pays as little as it does because it can. Almost the entire employment age population is qualified to work in a warehouse (I've done it). There is almost no competition for employees at that level, they're everywhere.

People who can code and run huge network operations are relatively rare, so they're paid a lot; it's competition for scarce employees. It has nothing to do with responsibility. If Google could pay minimum wage it would.

Not defending Amazon, just pointing out that they're paying the least they have to, just like Google is paying the least they have to.

So some poor guy who works for a company that doesn't make as much money as amazon doesn't also deserve a living wage?

Wages are about supply and demand. There is enough supply of the caliber of workers that amazon needs willing to work at minimum wage to fill their demand for workers.

If we think that amazon is making too much profit, and should distribute it more, then we should tax them more; that way, the benefit can spread to more people and not just the lucky ones who happen to work at amazon.

Because it's the government's responsibility to ensure people have a minimum quality of life. It's naive to expect corporations to act charitably — a company is an organisation mandated to make as much money as possible. Even when a company does seemingly charitably things it's rarely anything other than a marketing/branding exercise.

The case you link is about wage collusion on high-tech jobs, hardly the same as this case of minimum-wage workers.

Of course, if you have any evidence that Amazon is colluding with other employers of low-wage workers to keep their wages down, that would be germane and very interesting indeed.

Well they certainly shouldn't break the law as they did in the case you linked to. But if law is insufficient to ensure people that have a minimum standard of living — it's the law that should be updated rather than trying to shame companies on an ad hoc basis.
