As already pointed out, that's really twisting the premise here about the actions of Batman and others. Besides you kind of forgot that Dick's family, even when they weren't Romany, wasn't actually portrayed as well-off or anything.
Secondly, you're using the Authority as an example for heroes for the poor people and not being Noblesse Oblige? Really? Seriously? One of the most ethically challenged group of superheroes, who basically embodied the smug liberal heroes who consider themselves pretty much superior to everyone else and that they know what is best for the world because they have the power? Especially since Ellis also wrote them doing really reprehensible things in eliminating their enemies for 'The Greater Good'.
