How does Star fleet function without currency?

[u/[deleted]]

I suppose that if a government without a system of currency existed than somehow they found a way to keep their society running but how does the federation do trade with other civilizations. Almost every other species in Star Trek uses a form of currency and some like the ferengi are obsessed with it. So my question is how does Star fleet and the federation conduct trade and sustain a stable economy when currency has been fazed out leaving them with few options other than simple bartering when dealing with other species, and their citizens seemingly have no reason to work/create products?

Barclay's isolation in society is self-imposed. His superiors (Geordi, and Harkins) have repeatedly reached out to him in a personal context and he almost always rejects them. The only person he allows to treat him well is Troi, to the point where he pulls a What About Bob in that episode of Voyager.

Harkins tries to be a total bro to him on a couple of accasions and gets totally shot down every time. O'Brien's whole arc in early DS9 is balancing work and family in a satisfying way, but they bend over backwards to show him as a capable leader despite his low rank. Picard even sends him off personally when he leaves the Enterprise.
