A common theme in many published super teams are 'team gear'. Examples include unstable particle uniforms created by Mr. Fantstic or Edna from the Incredibles, access to secure communications earplugs, bases and vehicles. Bruce Wayne's wealth is the sfx but in many cases the entire team shares the HERO real cost. Same with the members of the FF and their unstable uniforms (I believe the tech was shared throughout the Marvel Universe). Champions Universe has many similar examples.
