Sure, but how the economy works is not explained. It's basically that first contact was made, humans realized they weren't alone, so war, poverty and money ended within 50 years, somehow. I'm sure it helps to have transporters, replicators and computers approaching AGI. But how everything inside the Federation just works is not discussed. I guess everyone just naturally wants to do what works out for society, somehow.
You might have here answer to the ”Where is everybody” question. Space is not economically viable. Not for us, not for the others. Not even in a billion years, literally.
It isn't discussed because the closest equivalent it can be compared to is communism, which is the last thing any network or studio wants to be seen as advocating regardless of how accurate or realistic or good or bad the depiction may be.
That doesn't fill me with confidence. Communism has not been successful, so it's not clear why or how it inexplicably works out well for Star Trek society.
