So why are master electricians a dime a dozen?

Someone said to me that a doctor gets paid millions because he studied for so many years.

So lets hear from someone who has recently completed all the training and years of practical to become a master elctrical, how long did it take you, and do you charge R2000 per 15 minutes and make them them sign a document which will not allow them to hold you responsible for any mishaps?

Do you feel you are worth the ridiculous low rate you charge and was it all worth the time wasted?
