> Children dream of big impossible things

That's cultural bias right there. It happens only if you tell them to dream impossible big things. If you don't teach children that astronauts exist, they will likely dream to become their teacher or the janitor at school, especially the friendly, nice ones.

I won't do a better job defending Jung's ideas than the man himself in his works, but just as a friendly reply: yes, but according to Jungs theories - these are archetypes - meaning all people have a combination of one _and_ the other. There might be people who refuse to grow up and stay in a kind of perpetual childhood with a failure-to-launch and never finishing their own projects (a good book about that is "The problem of puer aeternus"), and there are also children that grow up too quickly and start being cynical and sarcastic with a know-it-all attitude, and belief that nothing is worth doing and the world is going to shit. The actual human beings are a combination of those archetypes. So an astronaut is a cultural input, in the same way that saying that you have two hands is a cultural input, but what is different is the inner attitude - do you see a lot of potential to the point that you cannot make a decision between several choices, or do you see barriers and feel a loss of meaning. Again, a healthy combination is "best".
