Though it might fall under the umbrella of not spending enough money, I'd add that we haven't been meaningfully iterating on the technology and processes involved. One might even argue that traditional aerospace has been trying its hardest to reduce the amount of iteration/refinement going on to the barest of minimums.

This has kept crewed spaceflight stuck in a rut in terms of cost and risk. It's like if progress on the design of commercial aircraft suddenly slowed to a crawl in the late 1940s, putting us at mid-60s adjacent aircraft design in 2024.
