You’re wrong.
SpaceX has no meaningful competition.
Neither did Microsoft, back in the day.
Musk said the companies that made America strong are because of H1-Bs.
But America is only a shell of what it used to be.
Tell that to Blue Origin. SpaceX is where they are because of the people who invented, developed, tested, and reproduced their unique capabilities. If Musk couldn't keep those talented people, we'd be talking about their failures.
