I don't care what Wells Fargo gave back -- and I don't care if irresponsible use of governmental funds is the most time-honored tradition in this land. The simple fact of the matter, to me, is that in a time of substantial financial woe for many citizens, thanks largely to the irresponsibility of banks and other lenders, it is beyond unreasonable to accept a governmental bailout and turn around within months to lavish employees with a luxurious trip.
If that doesn't bother your conscience, then so be it.
Just remember that there are a whole lot of Americans, without jobs and struggling (to say the least) for reasons that largely were far beyond their own control, who could stand be valued. Sending bank employees, who are in a far better position than those people, to Las Vegas for a junket doesn't strike me as particularly compassionate or prudent.
Enjoy your taxpayer funded junket, though.
