Who is "we"? When engineers are not subject to licensure, don't be surprised when management, pushed by bean counters, let the bean counters make the decisions. Subject engineers to licensure, including ethics clauses, including clauses for building for repairability and minimum expected product lifetimes. Legally protect engineers from dismissal or retribution for invoking these clauses. Then see how much crap we co…
The UK has gotten worse and worse at large scale construction over time as laws and rules and culture have gotten more conservative. Near me a small bridge is being widened. This takes a year and a half and £160 million, partly due to well intentioned rules. For example, one that says you need to have two attendants guiding traffic at every location people could get to the site, which means 12 very bored men standing around all day doing nothing at the two intersections at the edge of the build site.
Rules made from our ivory towers can't take into account all the factors that will actually occur in our fractally complex reality, particularly as times and situations change.
The impossible task gets even harder when second and third order effects come into play. For example, if a license is required to work, that license can be lost if something ever goes wrong and firing for not approving something is impossible then a second order effect could be that engineers will have every incentive to never approve things, requiring every safety feature rather than taking the time and effort to determine which are needed in the situation. The third order effect is a gradual shift of engineering culture towards being more conservative, as being more than average levels of risk taking means you can't just point at what everyone else does and say "Best practice!".
