This is Nolan's first Batman film he's made post-recession, and it has a lot of post-recession imagery/themes. However, do you think that the recession actually happened in this movie universe? Is the imagery there just for the parallels to our real world problems, or is the imagery also a way to show that the recession did in fact happen and that Nolan just doesn't want to be heavy-handed with dialogue addressing it. Mark talks about there being 'no work' and the kids working in the tunnels like its a recent thing. Is that why the league are coming back now? Despite the lack of organized crime, corrupt bankers and the wealth gap that results from their actions is 'injustice' in the eyes of the League, and the only way to truly fix the system is to be reboot it/reduce it to rubble ("must be allowed to die", as Ra's would say). Or would they always have come back, despite a recession, because they think the system is inherently unjust/corrupt? I ask, because it seemed like Ra's was only referring to the influence of the organized crime/the mob back in BB, which Nolan wrote pre-recession obviously. Maybe it would take the recession for the league to see Gotham as a city with ample corruption via its bankers/rich.
