Of course this doesn't mean they'll freely drop a raise on your table. You go ask for it. The difference is you'll rarely if ever get assigned any bs targets assigned because the manager knows they don't have the control over you. You could walk out and they'll lose and you'll still likely win a job. It's lose lose for them.
Delicate balances exist here such as how much you get paid Vs the manager and what not. Also, this does depend on your manager not being self destructive.
Generally though I dont say this as something to subscribe to. And I'm glad I no longer deal with this. Good managers are good at coaching and leading. They'll do what it takes to make a team that's happy and does the work as needed as opposed to creating a single star.
But something I learnt as I gave up some of my youthful idealisms is that everywhere there are differing flavours of politics. As long as it's not identity based discrimination or anything else illegal:
Don't fight against it. The company doesn't need revolutionaries no matter how much better you think it'll make the company.
Don't fight in it. Most people get busy trying to play the system and get played instead.
Work with the currents. Take what you need. Call it a day. It's less "fulfilling" but at the same time it's always less draining and you get to be at peace with things eventually.
Like making a point with math for ram upgrades showing an estimate of salary costs discussing it alone vs just getting a new one. Or pointing out how say cost savings via getting rid of free drinks negate themselves with one additional turnover from interviewing time costs alone.
