What is the most lucrative path as a psychologist?

Aside from the traditional full time institution (130k) + our own private practice (50-70k) and maybe making 200k, how can we position ourselves to be most lucrative with our Ph.D. Degrees?

I know assessment, forensic work are very lucrative avenues.

But I want to hear from others who looked into this seriously - or who are making 300-400k easily with your psychology degree.

We all worked too hard for this degree. Having an open dialogue about making money is much deserved.

Thank you all!
