Helluvit is, after one member of the CEO Club uses an excuse like this out loud in public, it becomes easier for the rest of them to do it.
It's no less shameful, but after the pundits and financial analysts and other media hear the same mea culpa at a few quarterly results meetings, they stop making a big deal out of it, maybe even stop reporting on it at all -- it's not "news" anymore, eh?
The rest of the CEO's are just as responsible and should be held just as accountable as the first, but since they're pretty consistently rich folks with big ole generous parachutes in their guaranteed employment contracts, there really isn't that much "accountability" for the big bosses to begin with, is there....
