No. Kids are not stupid. You can appreciate environmental innovation while also recognizing that it is fundamentally, qualitatively different from doing difficult things in space. Do you look at the Mars Rover and say to yourself 'big deal, we have cars right here on Earth'?

I never claimed kids were stupid, my point is that a ton of resources were dumped into things like fan clubs, movies, TV and radio programs, toys, collectibles, children's books, keeping it in the news, etc. We even sent a grade school teacher into space even if that ended in tragedy.

Look at the cult of personality the Soviet Union built around Yuri Gagarin, yes people were always going to find space exploration interesting, but manufacturing a folk hero means even more people will, too, and it becomes something aspirational and seemingly attainable. The Soviets were not unique in doing this, the US did similar things.

I agree that all played a role. I'm just not sure that a similar PR campaign would be able to produce comparable inspiration from, for example, public infrastructure. There's no afro-futurist movie called "The Interstate Highway is the Place".

I think we were able to strike a chord with nationalist tendencies, which can be strong motivators, for public infrastructure during the New Deal era with the PWA and WPA and their associated propaganda. There was both a personal pride in bettering oneself with hard work, and larger shared pride of building huge, sometimes incredible feats of engineering, infrastructure that your neighbors and nation depend on, and quite literally rebuilding the nation for a new modern era.

There are already some related things in popular culture that seem to inspire younger generations, like new urbanism. The hope for a new way of living can be a huge motivating force.
