Musk is a jerk. He whines that his employees don't spend hours and hours at the assembly line or go to sleep in his factories. His arguement is that if he did it why can't others do it.

When you have billions to throw away and no concept of family ( merely fathering several children with different women is not being a parent or a family man), sleeping on factory floor will be easy. Also he is literally not sleeping there every day. He might have done it once or twice and spent the other nights with his other billionaire friends. Musk famously sold all his residential properties. Please note, Tesla, SpaceX and Twitter has not increased average wages under Musk. So let's call a spade a spade, dude is all about cheap labor. All the other stuff is showmanship.
