MD was/is a defense contractor first and foremost and the most important thing about defense aerospace is spreading the grift over as many congressional districts as possible. This makes total sense when your clients are 100% political. It makes zero sense otherwise.
Notice SpaceX can build big rockets on the cheap and keep a schedule? Yeah because they do everything in one place unlike NaSA and it's contractors that have to spread everything all over.
They cannot. Your statement is actually kinda funny, since "elon time" is its own meme and ULA uses "Schedule Certainty" as one of the main talking points to distinguish themselves from SpaceX (see  as an example of the ULA CEO doing exactly that on the SpaceX subreddit)
You mean compared to NaSA and it's aerospace contractors? Cause that's what matters.
