Why are the factories full of rude people now?

You are a prejudice! People in the factory have all kinds of levels, educational levels and social backgrounds, obviously they can't all be the same. And you don't know what kind of person you belong to, if you think the people around you are not as gentle and gentle as you think. Maybe you didn't blend in with them, and you have been out of touch with the masses. In fact, as long as we have more contact and know more about them, we will naturally talk more about their joys and sorrows, and there will be no such unrealistic sighs.
