What Makes Global Manga a Success?

Japanese news website Oh My News has an article that looks at what makes Global Manga a success, Manga Jouhou has the translation:

Japanese comics, known as MANGA, have become popular in Asia, Europe, and America. At first glance, it would appear that American comics would have the advantage because they use English, the world's most common language. Why has the world chosen Japanese comics rather than American comics? I think the reasons can be summarized by two points: first, the paper quality of Japanese comics is very bad; second, the Japanese comic publishers are better than American comic publishers.
