Your comment suggests that it's not opportunities that have been lost in recent decades, it's that the younger generations' expectations for what life owes them have changed.
That's not necessarily a bad thing, to a point. But it's not accurate to claim that the lack of dream jobs out there means that there are fewer opportunities for gainful employment than in generations prior.
Yes it's beyond possible, it's clear that's the case, otherwise there wouldn't be a shortage of plumbers given they can make money to live or even raise a family on.
But the sense of expectation has grown way beyond that, everyone wants to be an actor so they spend their time on tiktok, which is a winners market, and then the leftover masses that didn't build skills or work ethic complain about having to start at the bottom of the more 'realworld' pathways available.
For most of human history people just did what made them money to live, and were glad if they have the chance to do just that. Go and spend six months in a third world country and you will see this is true.
It does not negate the fact that there are high paying jobs available without college degrees.
How would this be doable?
Here's an alternative: everyone is responsible for himself, society is responsible only for the ill end disabled. Everyone is provided with a framework that enables him to learn, work and find himself a way to live and fulfill his wishes.
To suggest people just do the thing that makes them money highlights another problem if you ask me.
