Barely a day goes by without a story about how badly Amazon treats it's non-tech workers. Combine that with the stack ranking and, like you, I'm not convinced.
I would argue you can't fix the tech employment without fixing the rest. One bleeds into the other. I would never consider working for a company that can't treat it's more replaceable employees well.
