I think the "nothing I can do will change anything" is actually a predominant theme that's emerged over the past decade. I don't know if you've watched any of Adam Curtis' documentaries, but his documentary HyperNormalisation explores this in great detail (most of this documentaries have a similar theme I've found).
Edit: Apologies, I think I mean his documentary: Can't Get You Out of My Head. Essentially it asserts that all revolutions fail, because the people who attempt to overthrow simply become the new guard.
