... and a slight bit of off-topic but (I hope) interesting chatter
I looked at some of the dates involved. If my research is correct, Batman was first introduced in 1939 and Iron Man in 1963.
I also forgot to point out that Iron Man's eating vegetarian food (though he takes no stand on animal rights that I've ever seen) and running (a few) clean energy structures is part of his public relations agenda. The goal of these actions, ultimately, is to make Tony Stark less criticized and more popular with minimal work on his part - just as it might be for any businessperson.
I think I might use "bourgeoisie" a few of times when I mean "bourgeois"; sorry if that causes any confusion.
