The fact that Bruce Wayne made a company that creates things for helping civilians with everyday life when it comes to the super heroics. Not only does it give him something that can help millions of people, it also gives him a secondary source besides Lucius Fox for any new gadgets. as shown when the main characters made something that detects a bad guy by his/her odor and he uses it to find the Joker.
The way Van Wayne acts makes it pretty clear why Bruce Wayne would send him to another city given his...attitude.
Van Wayne is a Spoiled Brat who fires people for not letting him win in anything, even a petty game of a kids bow and arrow game. Makes one wonder why Bruce hired this guy, family or not...
