"Amazon has the right to do whatever they want to increase Shareholder value" No they don't, they still have to follow relevant laws. You have a point about universal healthcare, there's a few other things that could help in this situation though. In the EU I believe this would fall foul of anti discrimination laws (this affects only part time workers, part time works are more likely to be women). There are also protections against an employer unilaterally lowering peoples compensation.
