I argue that his cutting of the prices by executive order is a sign of PoLR. His poor relations are crippling him, signifying a dependence on and his inability to thrive without it. He's obviously a calculating figure.
I say, INTj.
(and I'll go a step further and observe that his poor relations have made him weak, suggesting 6th function exertion: his position with the rest of the world is one of weakness.)
Edit: wait, I need to look into this a bit further.
Here's an interview. He's obviously quite pathological.
...Very likely INTj-ENFj.
