That's because SpaceX is run with the goal of building actual space transit capabilities, not milking the taxpayer and distributing pork to as many politically influential districts as possible.

Until SpaceX and post-Apollo most of the space program was really a pork distribution system and a way to keep certain high-skill labor areas 'hot' in case we need them again. It wasn't a serious effort to learn about the universe or build a real presence in space. Some of that did happen but it happened almost as a side effect.

Edit:

Honestly I think SpaceX is just a decent aerospace company. They've appeared superhuman by contrast with companies like Boeing that have done nothing to innovate in the sector since the 1970s. When the comparison is with people completely asleep at the wheel, mere competence looks striking.
