I'm in the wrong line of work.
I've always thought that one of the primary impediments to my getting rich is a silly ethical objection to ripping people off. Consider, for example, the "Dual Beam Ultra Clarifier" from Bedini Electronics. It claims to "significantly improve[s] the playback quality of all digital media recorded on compact disc" by "polariz[ing] the polymer in such a way as to maximize the laser's ability to retrieve stored data."
They claim that not only will it make your audio CDs sound better, it will make your photo CDs look better! And all for just $189.95. Good grief.
