Not to mention the guild problem, like in medicine. I volunteered once to repair the local church's elevator as a favor. A simple task, but when I started checking into getting a certificate to do it as a professional service, it was ridiculously feudal and urban-oriented to a fault (apprenticeships, sign-offs from nonexistent journeymen, etc). The only 2 private contractors were literally written into state law as gatekeepers.
Infrastructure needs maintenance more than it needs paperwork, but in the 50s, there were plenty of hands-on ways to get the work done. Safety protocols led to credentialism, which led to exclusion and higher prices and profits for those First-ins who are now voting against cooperatives/unions as they age out of them. We still need protocols, but we don't need rigidity.
