The trading with a grocery store is heavily regulated as well. They have requirements for storage and handling, their scales have to be calibrated, and there can be very strict fines for things like screwing around with sale prices.
The behaviour, motivation, and goals of individuals (including your boss and CEO) working for a business very rarely has anything to do with the goals of the business itself. There is a lot of pretend going on, but that is mostly just surface BS. Why do you think CEO’s spend billions buying back shares instead of using that money to invest in new products and other innovations that will make the business more successful long term? Could it perhaps be (gasp! horror!) that they care more about personal enrichment than making the business successful long term?
You do know that your employment depends on the success of the business, right?
The relationship with an employee is no more adversarial than your relationship with the local grocery store when you buy a bag of potatoes.
