But ADHD has been shown to significantly affect income. It’s hard to excel in a high paying career when it’s affecting you strongly. It’s probably pretty hard to normalize for income, then, because it’s a confounding factor.
But that too largely depends on your parents income and wealth as well, ADHD is less of a problem in higher paying job than lower paying job. In fact, for higher paying jobs where you can delegate, AHDH can be an advantage.
If you can brute force your way through all the intermediate years to work your way up to it. I did that. It was brutal. I highly recommend not doing that unless misery is your thing.
