Amazon is one of the most evil companies on the planet and yet it’s not on your list but Costco is? Gonna have to completely disagree with you. Costco is probably one of if not the best company in the fortune 500. They operate and live by their code ethics to do the right thing. They’ve never ever had a lay off of employees, they treat people right.
You called them out for a subscription model, yet don’t understand what they are offering at all. What store can you shop at that offers products at zero margin? Costco’s yearly net profit is the number of members times the membership cost. Their entire business profit is only the $100 membership fee per person. That’s all they want to make from each person.
Edit: And then you have Amazon. Where they use people and dump them. Have a vulturistic operating model. They literally have meetings and design their software to trick people into buying at a higher cost. They’ll manipulate anyone anyway they see fit to make as much money as possible from them. They sell stolen and counterfeit products and they know it, they just let it happen because validating products would cost them money. They’d rather just say sorry if you catch them and give a refund.
