Keeping it brief SpaceX/engineer is genuinely trying to get people to Mars, largely driven by ideological reasons with extensive technical creativity/competence backing them up. Accountant/Boeing wants to make more money. Outsource our software development to guys in India bidding $9/hour? Awesome! That's another 0.037% profit, what could go wrong!? Something doesn't work? Who cares!? We're on a cost+ contract baby, what you call "failure to deliver", I call delivering value to my shareholders!
And then there's the politician. In this particular case, he's not only a life long politician but also 80 years old on top. The only 'bright side' is that, due to his political influence, he's gone to space before. On the other hand Charles Bolden was a genuine astronaut and absolutely everything one would think they would want from a NASA head, yet he was a miserable failure. It may simply be that political style leadership (even when not a politician) isn't really conducive to meaningful progress in modern times.
