Framing a realistic financial model for comic-book heroes

'Comics history is filled with characters who have seemingly bottomless pockets. Think about it. For years, the Xavier Institute has been sustained by Professor Xavier and Warren Worthington. Somehow, the nebulous assets held by these two men has paid for housing and feeding hundreds of mutants, building countless supersonic jets and periodically rebuilding a massive mansion when Sentinels blow it up.

Batman is able to create an arsenal of weaponry that could conquer a small European nation. He has literally hundreds of cars, jets, boats, explosives, grappling hooks, and bat-shaped shuriken that he created using his personal wealth. And his assets are so great that Bruce Wayne is able to build all of these things without anyone noticing that he is using his money to build ridiculous contraptions. This means that he can buy a Bat-plane without creating enough of a dent to arouse suspicion. That is a LOT of money.

But in Uncanny X-Men # 520, we see that wealth is, in fact, finite and that someone can't keep buying engines for a mutant asteroid indefinitely. It's nice to see someone in this universe who is in touch with reality. Even if that person is an immortal man in a white suit and surgeon's mask who dual wields hypodermic injection pistols'
