Fuck 'em.
When I called Chase about an issue with my account, I entered the byzantine world of a too-big-to-fail bank IVR system. I waited over 30 minutes just to get through and be told that they had to transfer me to another department. Another wait of 15 minutes. (Why not record the customer's phone number and call them back when a rep is available? I guess that would cost too much money.) Then, when I finally get the right live person on the line, she has the nerve to tell me they are recording the call - but when I told them I was also recording the call, they say that's not allowed.
This is not customer service - it's customer disservice. It's abuse.
There's not much of a battle to be had with Amazon on the retail side. Their profit margins are razor thin (<5% GP on retail). Prime certainly helps the bottom line, but they still have to spend money on every package they need to ship to you. Amazon makes most money on AWS by far. That's their big profit generator/cash cow. So unless you can convince businesses to give up on AWS, then no amount of consumer action is going to do much.
If you want to continue to use Amazon, make sure you buy from good American companies who make products in the USA when the option exists.
