A license does not the employee make.

Picture in your mind: unqualified apprentices legally in training, unqualified General-contractor labor legally doing electrical, and unqualified indepentant contractors also exempt from electrical certifications.

The playing field is getting leveled as the License board in my State estimates 50% of all licenses in all trades declare themselves exempt from workers comp. & employee certifications, but are doing projects that require qualified employees.

The underground economy is closer to 100% kaoss, but most licensed GC helpers, and 1/2 the electrical masters have already leveled that playing field, with their unskilled laborers.
