Any sort of work, in say, nonprofits, or public relations, or marketing, or consulting, or any institution where you're at a level of management where your job is to present plans and preside over their progress while being accountable to oversight, and these are examples of the top of my head where I have at least some sort of familiarity, are places where strong writing is an asset. And I'm sure I'm just pointing to a small slice that I know from my own experience. These aren't special exceptions. These are the norm. The counterexamples make me wonder what, if any, actual career experience people are actually drawing from to claim otherwise, or whether they have the perspective to understand how representative those counter-examples actually are.
The lack of responsiveness comments have to one other on the internet is disorienting to me, because I would have thought that this would merit acknowledgement. Your anecdote may as well have dropped out of the sky in response to basically any comment in this thread.
