Mmm, I see where you're coming from, and in a perfect world there'd be enough qualified people to do just that
I think teachers can/try to inspire people, even without those kinds of experiences but
it's very difficult to keep a teenager's attention like that, or not have it bounce off of them but it'd definitely be a useful thing for them to do (even if they have to make up stuff, like 'I once worked for (insert football team here), helping them add up millions of pounds and sorting out wages
and stuff' or 'I once fought a shark bare handed' because you always get people saying 'why is this going to be of any use to me?
'.
...boy, the education system is a can of worms.
