I think big corporations like Amazon should be more tightly regulated. They could easily afford cutting hours by 50% and quadrupling the pay at the same time, so workers wouldn't have to do overtime, but this is a exploitative and greed driven business. They also don't pay right amount of tax and because of that all workers are taxed more to make up for it.
Quick estimate: amazon retail had about about 8 billion in operating income for the six months ending in just [0] so estimate 16 billion a year. They also had 1,335,000 employees [0]. At least for the US, their starting pay is $18 an hour [1]. 18 * 40 * 48 is $34,560. If we assume 1 million of those are front line workers, just doubling their pay would increase their costs by 34 billion dollars putting them in the red by 18 billion dollars a year. Obviously pay varies by location so not a perfect estimate.
What? No they cannot. This is the document they report to investors, not the IRS, so it is global across all countries and subsidiaries. And their incentive is to report maximum profits to investors. What avoidance schemes and fake costs are you even thinking of?
