In most companies you feel you are working together for a common goal.

The common goal of pleasing the overseer? There are some good companies, but we don't have the stats.

when you move across to government or non profit you notice the absence of that feeling quite clearly

Any large company acts like a government. A small company owned by a large company becomes like this too.

After all if the company fails to lose your job, that makes life very difficult for you and is far more concerning than someone else making more money.

I've seen things. There are companies that produce essential goods. There are companies that use tricky market magic to determine who gets to own these goods.
