I have actually wondered about that many times. They don't have pockets and you never hear talk of money. If you have matter-antimatter, then you have all the power you need for anything at all, and if you have replicators, you can make anything you want, and if it's free, and no Democrats control it, then maybe you would have free everything for everybody. I dunno. What puzzles me is: no real visible force of laborBots, or anything like that.
Oh, wait...it's not real....
