I've always given the authors of posts like yours the benefit of the doubt as to what they do and don't understand about the point that was being explained to them. Therefore, I'll chalk this one up to you being disingenuous rather than dim witted.
'Knowing how to do things' implies specialized knowledge (as if you didn't know). Many (most?) managers come up way short on ANY kind of remotely specialized knowledge or skill. It could be anything from basic plumbing to creating a deep knowledge system. They make up for it, or at least try to by exerting pressure, using threats or denying privileges. I've personally experienced the gamut of these types throughout my career.
In their minds, the ability to negotiate trumps all others when in reality, in a highly technological and specialized society, we need all types of experts, not just those skilled in negotiation. It's your choice if you want to be dependent upon others to do the simplest of specialized tasks but it makes me uncomfortable.
I appreciate you giving me the benefit of the doubt. I've never been much good at knowing what people mean when they don't clarify what they mean. I'm neither disingenuous or dim witted, I'm just not very clairvoyant. When I read "people who know how to do things" I have to assume, as opposed to people who don't know how to do things, and I don't know of any people in productive society who fit that bill. Everyone knows how to do things.
Now that you've kind of explained what you meant, I understand you're talking about incompetent management. But here's the thing, that's precisely why free market capitalism is so great. If my company has managers who do know "how to do things" comes across your company full of incompetent managers, guess who's lunch is going to get eaten and who is going to walk away with the market share? That is, unless your company is being protected by it's corporatist allies in the government who can step in and proclaim it "too big to fail."
If free market capitalism is allowed to function, your company of incompetent managers is going to fail. Not some of the time but every time. My company might even absorb some of that companies more competent employees who "know how to do things" and they may one day become managers for me. Because, you see, I don't promote managers who don't "know how to do things."
But what is ironic is, you support Socialism, which is basically a bunch of politicians and bureaucrats running businesses they know nothing about. Making business decisions based on emotionalism and populism rather than knowledge of the function and objectives of the industry itself.
