"just learn a trade" is not an adequate, sustainable or reality based solution to job insecurity

This goes without saying, but pathways into trade jobs should absolutely be encouraged. Paid apprentiships that let young people enter those jobs are fundementally a good thing.

That being said, the problems facing job insecurity and unemployment, especially for young people require real legislation and cooperation from the industries to fix. It cannot be solved by just saying "why don't you do this". If life was that easy we'd be living in a utopia. What that legislation should be? I'll be the first to admit that I'm not sure but just claiming unemployed people are simply "lazy" comes largely from ignorance and ideology.

This isn't a thought out statement, it's just what someone "reckons" is the case based on half a glass of wine and a newspaper comic.

I sincerely doubt in many countries where this is a problem, there are even enough vacant trade opportunities to balance the scales back.
