This is a very old and popular meme. But as an "armchair epistemologist", who also happens to be growing rather weary of endless armchair economic and political critics "telling it like it is", whenever I encounter memes like this, my first question is always: "To what degree is this meme actually true?"

It seems like not just a fair question, but an important one.

> For people involved in the energy sector, but only really know coal, the only way they can comprehend maintaining and expanding business is to maintain and expand coal operations.

"the [only way] [they] [can comprehend]" seems like a rather extraordinary claim (and you know what "they" say about extraordinary claim), that would require rather intimate knowledge of the thoughts of of multiple people.

I'm curious, how did you come to possess this knowledge? By what mechanism?
