The Space industry isn't very profitable unless you get Cost+ government contracts. The margins are terrible. SpaceX's profit margins are either negative, zero, or razor thin. If Musk wanted high ROI, he wouldn't have bet on SpaceX. He's obviously doing it not because it's easy money, but because he's interested in space as a hobby. The first think he tried to do with his PayPal money was to buy an ICBM to fly a greenhouse to Mars. Does that sound like something that's a good investment? I don't think you're convincing very many people that Musk is doing this for advertising purposes. What's next, Musk gives a space talk to middle school students, and you accuse him of trying to recruit cheap future employees?
