Sure, there is a certain amount of work that is 'created' by unqualified fools making a mess of things.
The real security, though, comes after you fix the mess, or solve the problem the hack could not, and the customer realises that you have a skill worth hiring.
That's where the security comes in: being able to do something the other guy can't do. Sometimes this is because of training, your skill, or equipment you have.
Security also comes from being able to adapt. For example, near me they are building the "world's largest industrial park." Right now, electricians need to be skilled in handling big wire, big pipe, and digging. A few years from now, the sparkies will never see a shovel- they'll be doing control circuits and programming PLC's. Today's sparkies will either adapt- or move on.
