On Earth? Nothing. Food and convenience items could be created with Replicators and If you wanna some entertaiment Holodecks are free. The only thing that comes to mind is space travel, since outside of diplomats, Star Fleet and Auxillary people People that travel are mostly traders, not afficiated with Federation.
