Yes but that is because in a Musk company you actually get to build rockets, blow them and iterate quickly.
As Eric Berger states in his book. Engineers don't want to spend 10 years being responsible for the quality control of a single screw on the F-35 program.
At SpaceX you are producing rocket faster then anywhere and you always develop next generation technology.
But even among the people I know who work at SpaceX, the draw was "I want to work with Musk" rather than "I want to work on rockets."
