[Batman] What happens to Batman when he succeeds?

Assume crime in Gotham is reduced to nominal levels.  (Can’t eliminate every crime, but levels *can* be reduced.)  Batman’s rogue gallery is entirely incarcerated, dead, or reformed.  Justice is the order of the day over corruption in the government.

What happens to Batman?  Does he finally get to retire and become Bruce Wayne again?  Or does his obsession simply move to a larger and larger scale?

Several iterations of Batman retire for one reason or the other. Sometimes, like in the Nolan-verse, it's because he's completed his mission and saved Gotham from crime and corruption.

Usually when Bruce is done being Batman he quietly retires and keeps a very private life outside the public eye. That's one of the two constants when Bruce stops being Batman.

The other is that he remains vigilant, and isn't just ready to return to action as Batman, but to pass the cowl on to a new generation of crime fighters. 

With the introduction of Batman Inc., it does seem like, having saved Gotham, he's is ready to expand the Batman brand to the rest of the world. However Batman Inc. appears after Final Crisis and the Death of Bruce Wayne, which puts it relatively late into Batman's life. This is a period where not only has Batman succeeded in his goal of saving Gotham, but he's also getting older and his body probably isn't going to keep being able to be Batman much longer. Batman Inc. is really just another way for an aging Batman to pass the cowl on to the next generation.
