Obviously there has been a recent, rather major change in how the Federation (or at least Starfleet) economy works.
This is the thing that really gets me when it comes to sci-fi fandom. Sloppiness by the shows creators is so readily accepted as evidence of some unlikely plot event. What's wrong with saying that the writers describe a society with no money, although it's not clear when this was decided and there are several inconsistencies. Why resort to convoluted plot explanations?
Sorry, I don't mean to criticise.
