The only way to solve collective action problems in the real world is via coercion. That is, government.
Perhaps you have an issue with interpretation here. The pleasant story was the illusion here.
PS - I too loved the Richard Scarry books as a child and bought them for my children - and I'm not even from the US.
I think stories that describe better possibilities than what we have are useful cognitive and social tools.
Even though the children's books lack nuance. There are no problems with pollution and climate change in Scarry's world. There are no jobs that people do not like to do. Malice and greed is very limited, sickness never really frightening.
But still, the overall vision of goodness from the perspective of a child's innocence is valid and accurate. Adults at some point either just give up or mechanically hold on to dystopic beliefs because they feel it is part of their identity.
But it might just be a lack of imagination. Which is why hope and change always come from new generations, and the best elders can do is gently support them and step out of their way.
I don't disagree that young people (at least in the US) are told a lie like "Do what you love and the money will follow." I fell for that and tried to become research scientist, getting a far as receiving a PhD only to find that the funnel from there to a tenured research job was _extremely_ narrow. That's a giant waste of many motivated people's time. And it does need to be fixed.
But is the source of all this Richard Scarry books? I really doubt it. It's okay to give a rosy view of the world to children. Childhood is the longest and best vacation you'll ever take. But there does need to be an incrementally higher dose of "real talk" as children grow into young adults.
