So I know a few people who work for SpaceX (fewer than who work for Telsa), and they didn't have a harder time getting in than any other fashionable tech company. They had engineering degrees from the right schools and they acted like they read TechCrunch, Wired and Fast Company regularly without either hurting themselves laughing or loosing their lunch, and they got the job. If I had deep pockets and wanted to sabotage SpaceX I wouldn't do it by having someone fire a missile or something, I'd find an employee in the right position smart enough not to have dunk the kool-aid and senior enough to be tired of it and pay them never-have-to-deal-with-this-bullshit-ever-again-plus-worth-the-risk-of-jail-time money to throw a wooden shoe in somewhere. Much more expensive than $38k, but much more likely to go unnoticed.
