Where I work, I don't get a sense that we "thrive on kudos via performative actions" but I would say that ~15% of the employees are doing ~80% of the work.
This dynamic seems almost inevitable as a company grows. It's not necessarily bad, as long as the people doing the work are recognized and compensated.

Are the 15% getting 80% of the compensation, though?
Round your "~15%" up to 20%, and you've just discovered the Pareto Princlple: https://en.wikipedia.org/wiki/Pareto_principle, aka "The 80/20 rule".
