If only we could somehow make the public sector hire it's own personnel, pay it well and let it build the rockets instead of feeding either Boeing shareholders or the narcissistic idiot.
Most people convinced of public sector inferiority only perceive the hollowed out and thoroughly corrupted husk left by the neoliberal policies. Mostly because it's been systematically destroyed their whole life and they never noticed.
Or take ESA. They are currently struggling to finish development of Ariane 6. A rocket with tech already obsolete years before it is even ready to fly for the first time.
The crowning achievement of this system was the Apollo program. Which was followed up by the Space Shuttle, a system so expensive and full of compromises that it wasn't really good at much of anything except freezing the state of US space travel at the technological level of 1976 for thirty years.
NASA doesn't design and build its own one-off plane when it needs to send some people to a conference in NYC; they buy them commercial airline tickets. Likewise, purchasing launch services from a commercial provider is far cheaper and more effective than engaging contractors to build a rocket to spec.
