Unprovoked attack

I heard a financial analyst on NPR talking about the risky mortgages that have led to a lot of this market failure going on right now. He said:

Nobody knows what's in these bundles of mortgages. And they have a very, very low value because nobody can open them up and figure out which ones are paying and which ones are not paying. It's like Superman trying to look inside of a box that's wrapped in lead. You just can't see inside.

Isn't this crisis bad enough without maligning the character of Superman? Who amongst us can see through a lead box? Financial analysts are assholes.
