I struggle to understand what narrative you're correcting here. "We" in this context seems to collectively mean "humanity". Markets, media narratives, etc. are all run by humans. That's "us", whether or not you personally want any of the blame/credit.
"We" don't. Media narratives over-focus on individuals and personalities because that's what humans focus on.
Markets can overreact emotionally on daily headlines and weekly narratives but tend to correct quarter to quarter. There's lots of data and examples: Apple after Jobs, Microsoft after Gates, etc. Even after losing iconic, long-time leaders, most industry-leading companies continue to make even more money, more profitably than ever over the following decade.
