It's not your job to feel engaged. It's your employers job, your bosses. You can feel how you want to about it.
While objectively true, it's silly for employers not to exploit the psychology of the engaged employee for the employer's gain.
I disagree. It's exploitive for people in a position of power to exploit the psychology of the folks that are in their care. You use the word exploit, exploiting folks isn't good or moral, in any case. It's never ok to exploit folks.
If we say we are aligning the interests of the employer and employee that's different. If we are saying a rising tide raises all ships, we all do well when we all do well, etc. That's different. None of that is exploitive, it's inspiring. There is a difference between inspiring and aligning people in powerful ways, and exploiting them. One is ok, one is not. One leads to true long term success and prosperity, one leads to short term success but long term failure, a flash in the pan.
