Seems to be the same problem here in the US. I'm in my early 40s, and I'm one of the younger talented techs in my branch. The younger guys have a high turnover rate, and very few seem to have any ambition to progress beyond being PM techs. I don't get it honestly, I was rebuilding motorcycle engines when I was a teenager, and when I landed in this career in my mid twenties I never turned down a hard job, and viewed them all as an opportunity to learn skills that that would eventually earn me more money. It took longer than I would have liked, but that strategy paid off when switched employers. As hard and dirty as this job is, I've had far worse jobs that paid less. At this point I'm making more than many college grads stuck in the cubical jungle, I never had a student loan to pay off, and I know more about motor control systems than some of the people who design them. I don't know what it will take to get to get more talented young guys In the business. I think it will only get worse as time goes on.

In short, the shortage is here now, hopefully we can make it pay soon.
