A way to help popularize the ideas of science for the people instead of for profit maximization.
This, by the way, was one of the subtexts of Gene Roddenberry's TV series Star Trek. It was set in an Earth future that had no ads or clothes with brand names emblazoned for all to see, no private "SpaceX" interstellar ship (even tho it was called Enterprise, it was far from a vehicle for advertising capitalist stuff... Or representing Earth Imperialism). When, in the series, the Trekkers did return to Earth in their time, there was no money and no wars and no crass commercialism. Forced to face racism and sexism via the realization that there are more advanced beings that are not white or Asian looking or of a dominant "Earthmale" gender, in Star Trek's time, racial and gender discrimination has been almost wiped away. Later in the series we saw women, Black and Asian star fleet captains and admirals.-- Sam Anderson
