Conflict of Interest Carol Browner, czar

Odd, a fairly close reading of the U.S. Constitution reveals no provision for the office of ''czar''. I guess it is possible that I missed it, but it is more likely that such a thing was never imagined by the founders, nor by most Americans then or since.
Yet we seem to have acquired a number of them. The experience to date confirms my belief that this is the wrong way to go.
Case in point, one Carol Browner. You may have heard the name. Ubama stuck her into one of these 'czar' jobs, one long on power and short on accountability and ability to pass Constitutional muster. And, apparently, no more possessed of any ethical considerations, putting her in good company in that band of thieves.
Here's a story worth reading.
This is progress?
