Money doesn't even figure in my opinion. When was the last time that astronauts were on TV? A major broadcast? When's the next planned mission that people care about? Astronaut is possibly the most elite and difficult to obtain profession in the world but most of that elite selected minority doesn't even make it into space. Over most of my life you couldn't even dream of being an astronaut because the position was full and they weren't holding candidate trials. They just aren't relevant in most kids lives except as a vague abstract concept on the periphery.
Money beyond necessity means as much or as little as you individually value it to mean.
And there is not "a world where money means everything" vs a world where money means less, money is literally an abstract representation of your trade capability with other people. If you want to trade things directly without the usage of money, you're free to do so at the loss of a convenient abstraction. If you'd like to choose a different abstraction, like gold or real estate, you're free to do so. If you don't want to trade goods and services at all and do everything yourself, you're free to do so at the loss of convenience that comes from the division of labor. If you want to find a community of like-minded people that can pool available resources to grab a plot of land to collectively self-sustain, you're free to do so.
So no, this isn't some "we live in a society where..." situation where kids now want to be YouTubers because that's what society "values." The market barely values it, there are probably like 10000 successful YouTubers. Choosing that as a career path, given that they are primarily motivated by money, would be an idiotic decision. They're clearly motivated by other factors, like fame, peer adulation, flexible hours, and interest in the job itself. If money was the primary motivator, they'd choose almost any other profession.
What about fame? A modern Youtuber can sometimes get close to the fame the early astronauts received. Sense of accomplishment and self-worth? Money in a lot of ways is a shorthand for all the other things people value. For instance a famous astronaut back then or youtuber today is going to have access to pools of acquaintances to seek out solid friendships that most people will never know.
