Can someone explain to me why, when they go to all the trouble of making CDs relatively tough, jewel cases are the single most fragile item in the known universe?

I'm sitting at my desk, surrounding by a stack of perfectly good CDs which are (barely) contained by cases with broken hinges, missing teeth, cracked covers, etc. And I frequently have to clean the showers of tiny plastic shards from my desktop and keyboard.

Who the !@#$#&^^%#@! designed these stupid things? Are they still employed? Why? (I can dig planned obsolescence, but people don't buy new CDs because the *case* is broken.)

Thanks, I feel better now. Now if I can just dig out the plastic bits imbedded in my arm ...
