Sure - that doesn't seem to be the case with Ms Lawrence, although maybe she just has superior marketing. The counter argument though is that without a reasonable level of empathy and emotional intelligence, it would be impossible for an actor to effectively inhabit a character of any depth. So while your argument may well fit with some of the actors making their millions from Michael Bay movies, I suspect it would be nigh on impossible for someone "intellectually and morally vacuous" to succeed in the majority of movies requiring anything more than biceps, boobs and one liners.
