Star Trek is very explicitly a post-scarcity society. There was an episode of Next Generation where they revive some Earthlings who had successfully frozen themselves in the 20th century.

One was a businessman who was excited to see how much the stock portfolio he had put together as a long term trust had fared. Picard had to gently explain to him wealth and money were no longer a thing.

Last episode of the first season.

Of course the Picard series itself then thoroughly destroys that thought by going on and on about money.

In all fairness, between that episode and Picard, the Federation had extensive contact with the Ferengi.
