So the article and study argue that millennials aren't actually lazy, because it's young people in general that are lazy (about work). Literally. It's a dystopian argument. They're saying that it's nothing specifically to do with a certain generation of people, it's just that young people on average are more lazy now. So millennials aren't lazy, definitely, only young people are, which millennials are, but millennials aren't lazy. It does your head in trying to follow their "logic".
