That's a good point: if your job involves exercising power, and you really like that part of the job, you are liking the power. In theory RGB could have done all the other aspects of the job by working writing a blog on law opinions. The only difference would have been that her opinions wouldn't have shaped US law. It would seem that the exercise of power over people is the desirable part for them, just like the exercise of power over wood is the desirable part for a carpenter.
