I looked this up when I ran across a Wikipedia sentence that said something like 'The only species of waterfowl endemic to Scotland is...' Since then I've been listening and have noted that many people use this term to mean 'inherent': 'These problems are endemic to our group', says this Cheese Lord or that on a regular basis.
It's not a great transgression, given the examples Merriam-Webster lists above for 2b—the latter of which already veers slightly south of their given definition!—but speaking of self-indulgence, it's a skosh presumptuous, for example, to hold that administrative paralysis is endemic to one's own group, as if no other group is so bedeviled. 'These are problems endemic to self-governed groups' is truer to the original meaning of the word.
I sense meaning in flux. Let me peruse the literature.
