Under-appreciated factor here: a hell of a lot of people—even in the corporate world, even (somehow!) college graduates—are shockingly bad at reading comprehension (which is simply being bad at reading) and at writing clearly (or, simply bad at writing).

I suspect the population for whom this holds isn’t much smaller than the famously-a-majority “bad at math” set, and the difference in visibility of the issue is because the “bad at literacy” folks don’t volunteer their status as readily as the bad-at-math folks.
