Take a look at the mining industry. They haven't reduced qualifications required. They have raised salaries to attract qualified workers.
Mate I have spent the last 5 years in, and trying to get out of, the mining industry.
I promise you that the day I started in mining (with the same company I had previously been Chief Pilot for) I started with no quals or relevant experience and I doubled my wages overnight.
You cannot lower minimum qualifications from Zero for mining technicians, or a trades certificate for tradesmen. Doesn't matter if the ink is still wet on that certificate either - it's like QF taking SO's straight out of flying school with a bare CPL.
Can you imagine doing a 3-year Electricians apprenticeship after finishing year 10, and then at 19 starting on a salary of $90,000?
Mining is a dead-end job for morons. I no coz I are wun.
