They only make $5000 per worker per year or so, given that the stock market has consistent returns of about 7% lately it's getting to the point that it would be better to put that money there was opposed to paying workers with it for such small returns.
$11 billion divided by 650,000 workers isn’t $5,000.
In any case, the point is that they can pay more. You can quibble over the amount. You can argue about whether or not they should. But they can, in the same way that I can buy an entire truck full of peaches if I decided that would be a good idea.
We are back at run the warehouses at a loss. The profits from AWS have nothing to do with the guys packing boxes and moving the profits from there to them is running it at a loss.
