There is no currency in StarFleet and its participants, read and watch it again. No money, no currency, no commerce, only the smart allocation of resources. The only species using money are the Ferengi, which is a representation of capitalists.

You have never watched Star Trek, because on season 1 they unfroze a buncha tycoons and the first thing they asked were their finances, but in the future (where values from the left dominate) there is no money, all people are accounted for and everybody is free to follow their passions and dreams. Gene Roddenberry was described by his wife as MAOIST. Star Trek both the original series and the next generation were media responsible for progressive breakthroughs on the culture, first white-black kiss, a lot of racism and homophobia references as primitive and backwards.

You should watch ST, maybe you learn a thing or two.
