'fair and orderly auction market' is a phrase that hardly describes the full reality of the system. Markets are only as 'fair and orderly' as the people whose practices make them up.
Consider the headline on the front page right hand column of today's WSJ: "Why the Bad Guys of the Boardroom Emerged En Masse." Praytell, if they emerged en masse from the boardroom, is middle management exempt? And if they emerged en masse on Main Street, is Wall Street exempt? And, if they emerged en masse on one side of the 'Chinese Wall,' is the other side pure? And, if they emerged en masse upstairs, is the floor exempt? (and, tangentially, if they emerge en masse in the private sector, is the command sector exempt?)
In the days of Beaver Cleaver, the specialist system was, I'd guess, much closer to it's ideal. These days, we live in a different world.
