It seems like only Superman is aware of how he and his allies on the Justice League are failing the very people they've sworn to protect. After being made aware of the common person's plight, the Man of Steel realized a serious flaw in the League's methods.
By uniting their forces, the members of the Justice League have been able to do much more good than they have individually. Forces that threaten the universe or even the multiverse find themselves challenged thanks to the combined efforts of DC's greatest heroes. Since they first banded together, the Justice League has fought Darkseid, the Anti-Monitor, the terrifying forces of the Dark Multiverse and other evil beings whose power is almost impossible to comprehend. Thanks to the League, the citizens of the DC Universe can live on in peace knowing that someone is looking out for them.
However, Superman may be the only one aware of a deep flaw with the way the Justice League operates. In Superman #700's short story, "Grounded Prologue: The Slap Heard 'Round the World" by J. Michael Straczynski and Eddy Barrows, Clark is called out by a grieving widow over the loss of her husband. She believes Superman’s powers could have helped her husband get rid of a tumor in his brain, but the hero was nowhere to be found when she looked for him. This gets Superman thinking on what he's doing to actually help the people of the world on a level that means something to them. He consults Batman who believes that the team is doing just fine protecting the world from villains. Flash also doesn't seem to understand what Superman means when Clark asks Barry what he sees in the world as he's running around.
What Is Superman's Real Issue With The Justice League?
To the hero’s credit, Superman had just lost New Krypton, a revived version of his home planet grown from the bottle city of Kandor. Not only that, Superman was lost after a war between Krypton and Earth made him question his place in the world. Clark felt that the woman that called him out was correct because he had focused so much on the big picture, he had forgotten about the little pieces that make it up. Unfortunately, it doesn't seem that the rest of the League is capable of a similar introspection.
Granted, it’s important that the League use their gifts and abilities to protect the world. The Justice League faces threats that regularly put the DCU in danger, and they’ve successfully pushed back against almost every major attack. However, Superman recognizes that the average citizen has concerns on a more personal scale. The people can’t worry about alien invasions or demons when they’re also worrying about the stability of their loved ones. It seems that out of everyone on the Justice League, only Superman understands that the Justice League needs to examine who they’re fighting for, rather than what they’re fighting.
