The Trump administration is a loyalty-based hierarchy. The intelligent advisors know that it is better for there careers do demonstrate loyalty than actual do anything to improve his policies. This is not rationalists paradigm, it’s a survivalist paradigm.
In fact the reason why it’s so bad now is that he blames his (more intelligent) advisers in his previous administration for his problems.
There has to be more than a few of them, right? They could halt or correct this agenda at any time they choose.
