I don't argue with your point regarding how many engineers have their PE. I don't have mine.
My point is that accreditation boards and trade unions can help set standard minimums of what an engineer (or trades person) will know going into a job. Of course employers can ignore them, but in general those standards help bring consistent expectations to a given trade.
