Oh, the writing thing is just a personal quirk for me. Doesn't detract from others too much, I hope.
And batman was able to get the BEST training because he had the resources to travel... but all-in-all, his training is a result of diligence, not wealth. It's the time he puts into it.. the endless hours. The fact that every waking moment (and sleeping) of his life is spent on bettering himself for the sake of others. He could have done it as a poor man, and been just as good, because it isn't necessarily WHO trained him, but how much of himself he put into it. I'll cite others around him who hadn't his privilege, but can hang with him.. Dick Grayson (Robin/Nightwing), Jason Todd (Robin/Red Hood), Tim Drake (Robin), Stephanie Brown (Spoiler/Robin), Helena Bertrelli (Huntress), Barbara Gordon (Batgirl/Oracle), Cassandra Cain (Batgirl)... In the case of the latter, there is a poor girl who grew up with the most severe of training.. and can match Batman easily. But the thing about all of these people is that they spend EVERY moment training, or thinking about training. They made their life's mission to help others, and nothing can get in the way of that.
I'm not saying that that should be us... As Leon said, we aren't superheroes and we aren't vigilantes. But whenever I get into a slump of my training, I go and read some Batman comics, and I realize what can happen if I'm NOT strong enough, fast enough, etc.. And I realize that I can always devote more of myself.
