Too often I have seen the results of "minimal" standards. My 401k is currently the results of "minimal" standards.
My neighbors house and all his problems is the result of "minimal" standards. It is all code for sure but he is having a lot of problems. Thankfully he has a homeowners warranty and is making the contractor fix all the "minimal" standards.
Better to over build than to save money and meet the bare minimums.
They weren't comming over to fix the minimum standards they were fixing the shoddy workmanship. Who knows maybe they used the cheapest devices that they could find and the devices are failing not the workmanship. But alas you have your opinion on things and I have mine. You are allowed to have your opinion.
