Which is precisely the point. When you say a nation is "corrupt", you're generally referring to one that is notable for that factor. Because otherwise the term is meaningless (because every nation does have corruption). As a complementary example, you could argue all legislation is authoritarian; but describing a nation as "authoritarian" in the general (vs specific, as in certain laws/bills) goes above and beyond "normal" legislation.
