What is it then? What is real? It has to be environmental and safety regulations, long running environmental studies, general bureaucracy and NIMBYism holding construction and infrastructure back right? That’s what held up the high speed rail in California (along with funding factors). We’ve always had unions so that shouldn’t be it.

I mean you're demonstrating the exact problem right here: you aren't talking about any specific instances or processes, just vague concepts.

"It's regulations" "it's nimbyism" "it's environmental studies".

Concepts. Not the real actual implementations, their stakeholders and their impact on the project.
