All of those languages listed (that I know of) are what are called synthetic languages, meaning they tend to use words made up of many (in the case of polysynthetic languages, very many) morphemes. Thus concepts that are expressed in an isolating language using several words — happy at his suffering, so bad it's good, mid-life crisis, to use a few examples from the article — might be expressed in a synthetic language with a single "word", but which is still composed of several meaningful morphemes.
Basically, "words" in these languages don't fulfill the same function as words in English, so the comparison isn't really valid, and the fact that there isn't any single-word English equivalent isn't very interesting. Not to say some of those aren't nice words, of course.
