Is it a bad idea for the Home Depot to give seminars for work which should be done by a skilled electrician?

I am an electrician and disagree with places like the Home Depot giving seminars on wiring. A little knowledge can be dangerous and I wonder how many people have burned down their houses or electrocuted themselves after taking one of these seminars. What do you think? Should they be allowed to give crash courses in something that should only be done by a cerified electrician who has spent YEARS learning his trade as opposed to a few hours on a Saturday afternoon?
