I just have to say, while most companies operate exactly how you describe, that is certainly not all of them.
It’s sad. Even the word ‘company’ should mean that you’re in this together. It’s what it means in militaries. It’s what it means in social settings. It should also mean it in businesses. It used to, at one point. At one point people actually did work together and enjoyed a fair return on their labor. It was the only way to reliably get things done. People had to be dedicated.
