This is not a "sort of people" problem. This is a metrics problem.
It's not only developers who are evaluated by using useless metrics that don't track the value you add to an organization. Low-level managers are too.
Low-level managers need to evaluate the people assigned to them, they need to evaluate them objectively, and they need to give an unbiased and objectively verifiable score. This means something they can measure, such as metrics or verifiable goals.
If low-level managers cannot do this, they will need to answer why they gave X and Y this score whereas poor little Z who outworked them both was scored lower. Not being able to objectively justify a score is a problem that no manager wants to have, as this is a major liability.
Hence the bullshit metrics and absurd goals. They need something on paper to back up their decisions. A manager might be fully aware that you unblocked half your team members throughout the year with critical help, and that you are the go-to guy to solve critical issues. But if your team members close twice the tickets you did, they will have trouble justifying you are contributing as much as them.
