"professional slacker who knows all these psychological tricks"

You are my spiritual brother!

Same here...

I was really motivated in my 1st and 2nd job after leaving uni. Then the gravity kicks in, realized that noone wants me to work extra hard as that only makes other people look bad.

Just lean into that. Start automating peoples jobs or making their jobs irrelevant. The management will take note of the concerns of the others and put you in your own group. Now that you have established that you are 5x more productive than the other employees while only making 20% more, management will not care if you slack off and only work 5 hours a week.
