The Pilot and Technician Outlook is Boeing's long-term forecast of the demand for pilots and technicians and its estimate of personnel needed to fly and maintain the tens of thousands of new commercial jetliners expected to be produced over the next 20 years.

With the dumbing down of the "technician" by industry and regulators alike what percentage of these "technicians" would be trained and experienced enough to be able to certify for the maintenance performed by themselves and those that require supervision. CASA and the local operators are perfect examples here for the race to the bottom to dilute the industry experience required.
Figures are rubbery at best.
