The ways of earning and living for young people have changed drastically since we moved from the agriculture(field) era to the technological( Internet money) era.

The concern is very alarming this is because if limited young ones are willing to work in these traditional structures (Oil, Agriculture, manufacturing, etc.)
It is true that nowadays the younger generation tends to choose the job they want which is very promising and doesn't drain their energy rather than traditional work because nowadays the progress of the digital era demands that the younger generation learn a lot of new things, but there's nothing wrong with that. The question is, can we survive in this current era without anyone or few taking up the traditional work sector?
It's hard to say because the living system becomes unbalanced and creates difficulties the future.
