Why is it that he is meant to be some selfless Superhero and yet he lives in a mansion and is a billionaire? Sure he needs money for his "other life" but why doesn't he spend some of his money on all the people starving in the world? Like when Hush posed as Batman and gave away I believe 1 billion dollars a month. Of course he would run out of money quickly at that speed but he could donate at a slower rate. He would also need some in reserve like about 100million dollars. But he can still donate a hell of a lot.
Here's another one. Why doesn't he use a powered suit? I know for street level and patrolling it is better to just go with his costume but what about the rest of the time? He could where a suit for people like killer croc and Clayface. Also why does he need to train a youngster for several years when he can find the most morally appropriate adults and give them powered suits. He once claimed (can't remember issue number) he had reverse engineered the suit of every powered suit villain in the JLA database. He normally uses it to disable the suits but he could also use it to build some powered suits by taking the best parts from several different villains designs.
