Yes he has. All the trades pay very well once you get your license.
The whole license thing is a racket. Define pays well.
I wish my trade paid better, I was painting for the State, on bridges, overpasses, and in treatment plants. $45 an hour, dangerous work at night and sometimes over highways. It is not a lot of money really. With OT, I could make $100K. School teachers make that much, and with permanent jobs and great retirement, while working less than 9 months. In my state, they allow the teachers to draw unemployment during the summer now.
