[DC]How does the richest human beings' wealth fare on a galactic/universal/etc. level? Is there a way to measure and compare wealth across different planets?

To illustrate the title with an example: we all know Bruce Wayne is one of the richest people on Earth, but is he also a one\-percenter in the entire Sector 2814?

On a wide scale, money probably does not matter nearly as much as your material resources and your people. 

Gorgolons from sector 50000330 don't want dollars, but might happily trade a few warp drives for DNA samples, art, science, borium, that iron asteroid over there, a bunch of venusian methane, or maybe even anglerfish livers, which are rumored to work as aphrodisiacs for them. 

Aliens capable of interstellar travel either want energy, matter, or something that they can only get from living planets. Earth's "wealth" would be our ability to produce rare items not found elsewhere. DC earth has a variety of resources, such as capes, magic, lazarus pits, geniuses, and more. Does DC have an equivalent to adamantium/vibranium? Aliens could want that too.
