The real hero of the Dragonball series writ large is undeniably Yamcha, who not only got a stable job of his own but had reached a true, enjoyable profession that isn't simply sponging off the livelihood of others or roughing it in the wilderness, and/or living off prize money. Mind, this is the man who started out as a cutthroat living in a cave in a desert who made a living mugging the occasional passerby. Guy really turned his life around.
Though, he did spend a fair amount of time mooching, and I don't know how much fulfillment he got in his sports career.... which must be the most casually easy thing for him considering his stats, it's really unfair for a chi user to compete in baseball!
Meanwhile, Krillin got a job as a police officer (where it's *perfectly good* to be unfairly powerful!) and has a loving relationship with his family. Or there's 18, who has a loving family and got her money off Mr. Satan ^^
