It should also be noted that tenure does not guarantee funding. A tenured faculty member who adopts "slacker" behavior will likely see their lab/group eviscerated, more "service" obligations heaped on them, and their job progressively becoming less fun. Additionally, "tenured"/"non-tenured" is not a single binary switch in terms of prestige. Even with tenure there's things to be striving for.
