Would you think it's a good idea if there were a Presidential Review Board that is named by the President? After all he/she is elected by the people!
The whole point of a review board is to be independent of the authority it is supposed to review. So, a police review board mustn't be selected by a member of the police forces, even an elected one.
While what you're describing is a bad model when you want independent review, its exactly how many (all?) of our federal oversight agencies work.
The FAA, USDA, NTSB, etc all regulate industry by quite often asking the industry what regulations are needed and how to enforce them. Its common for industry to even be expected to enforce regulations on themselves, leaving us with situations like Boeing.
I'll be very happy if that's a broad sentiment reaching beyond HN.
Our regulatory agencies are worse for all of us when they're owned and operated by industry.
A peaceful change seems really, really tricky. Its so much easier to create regulations than remove them. Congress would have to ignore industry money and want to push through change, these agencies would have to be rebuilt from the ground up, and industry would have to deal with all the churn without cracking our economy since GDP and employment numbers seem to be the only things that really matter to our executive branch.
