As a taxpayer, I find it a little irksome that the U.S. Treasury is marketing those shares at such an enormous discount to book ($58 and change). I would think the Treasury could do a lot better than that.
The fact that they could unload all those shares for $30.50 to subscribers on a Sunday evening, and then have them trading at $32 within 48 hours on the secondary market is an indication that the Treasury, while they might be making a profit, is not getting as much as they could be getting.
