You know what, you mention something that has pissed me off with a recent evolution of American culture by citing two examples I find relevant, so I'll expand.
Star Wars is a 1977 movie. It actually consciously uses the codes (and copies some scenes!) of WWII war movies. What are the heroes doing in it? They are helping a big organization (the rebellion) fight a formidable enemy. Just managing to flee from such an enemy is a heroic endeavor.
Compare it to today. In most, if not all, blockbuster movies, organizations that the heroes belong to are either incompetent, corrupt, are a hindrance when they are not the main antagonist. There is a total loss of the idea that belonging to an organization can make sense and can help a personal journey.
Sheriffs, policemen, journalists, they used to be the heroes of various fictions. Now we seem to refuse to believe that these can be heroes. We refuse to believe that collaboration with a team can be effective. Actually, now it is a trope that if the hero has a trustworthy associate, treason will happen some time in the storyline.
And somehow I understand what it is about: people are disgruntled with their work. They realize the company they are working in is not helping their personal hero's journey and hindering it. But really, the reaction that "therefore I shall do it all alone" is really bad.
