Generally speaking:
1. US corporations hate unions.
2. US corporations constantly try to roll back employee rights and benefits to a status of decades ago.
3. US corporations constantly try to roll back environmental and industrial regulations that exist to protect the lives of their employees and their health.
4. US corporations only pander to their high-ranking executives. Trickle-down theory has never existed in most US companies.
5. US corporations fetishize technology like AI in some corporate utopia future of unlimited profits which will only be funneled to the already mentioned high-ranking executive and not to their worker base.
