Contractors, not Congress, have the best chance to put a stop to the commoditization of their craft.
Do a Web search on “reverse auctions” and you'll find abundant commentary about what a bad idea they are. AGC, MCAA and a horde of other construction trade groups are rightfully indignant that reverse auctions reduce their members' hard-won skills to commodity status.
Yet, genuine commodity producers scream just as loudly. You can even find articles by procurement authorities who caution that reverse auctions don't save as much money as assumed and ought to be used sparingly.
