Like the detail that one of the most egregious episodes from California HSR involved a Spanish company that performed excellently on rail projects in Spain. Overall, this piece makes a strong case that the problem is specifically NIMBYism and loss of government institutional capacity.
I think the million dollar question is how government organizations can hire and retain better. The current situation looks dire. Obviously a charismatic leader with a broad anti-NIMBY mandate would go a ways at getting competent people to want to work in government. You saw that succeed on a small scale with orgs like US Digital Service.
The elephant, after that, is merit-based pay and promotion. Someone needs to sell this to the public. RN literally random cops and plumbers make mid six figures thru overtime while the directors of $100b mega-project are low-energy lifers making less than that. That's not gonna work.
