Note I pointed out how they tend to *exclusively* grab credit as if they are the *only* ones that matter. There is a role for 'leadership', but the leadership role is more often than not lucked into by either being born into money, or having rich friends rather than particular skills.
In terms of "strategic" direction, this is all too frequently bullshit, with wishlist thinking rather than insight. One example, an executive laid out his strategy, and after peeling away the rambling, the core "strategy" was "increase price per unit, increase units sold, and reduce costs". The leg of making this work was left to vaguely "the team has to innovate something that makes the product a must have", no inkling or suggestion as to what such an innovation might be, but now that he offered the direction "innovate", now it can happen, as if people weren't constantly trying to do so anyway.
So when it predictably failed? Well, unfortunately his team was unable to execute on his brilliant strategy. If it had passed? He would have had the courage to toss aside conventional wisdom that you have to balance volume and price and expense and lead the company to amazing success, and the guy who actually came up with whatever mythical thing only did so because that guy ordered him to "innovate".
Decades in the industry has had me working closer with these "leaders" and the closer I get the more reinforced the impression becomes: these people are egotistical glory hogs that got their position thanks to their family or having the right college friends, or being a background character in a popular product or company and milking that for sucker companies that see a brand like Microsoft or Google in a resume and assume that person must be the most awesome person ever.
I have met good leaders, but they tend to also have the chops to do actual work in the field they lead, even if they don't do it anymore. A good leader needs to have developed some innate understanding to have an vaguely accurate gut feeling for how the organization is doing, to know who is actually doing well or not, knowing how to correct a team that has gotten wrapped up on stuff that doesn't matter. Most leaders are essentially gifted their position by other leaders that don't fully understand things and it becomes a lottery for who gets success and sometimes global recognition like Altman, or who just everyone gets to see as a blatant fraud, like Milton.
