I mean there are pros and cons to many things. What I mean by underrated is just that a lot of people say "oh duplication, how wasteful" and don't realize the benefits that may exist in redundancy and diffusion. I think the US would benefit right now if there was more "duplication" in the sense of greater diversity across many industries. More car makers, more film studios, more news organizations, more social media companies, more record labels. Not more stuff --- not more cars, more films, more news, more social media, more records --- but just the same stuff spread over a greater number of entities. The consolidation we've seen over the past several decades is a bad thing.
