Both true and not true. Nearly every job requires some skill, the question from an employment point of view is, "How much does it take to acquire those skills?" At my last job I could take a High School Junior with a 2.0 GPA and no work experience and have them competently monitoring the arcade in one 4-hour shift. Maintaining the games took 4 years of technical schooling and a year of on the Job training. I got paid more then the game room attendant.
