Do you think the decreasing interest in reading is a reason why so few learn languages to proficiency?

Both on the internet and in the real world attending classes at all kinds of levels, I find it interesting that I barely meet anyone that reads or has an interest to read anything else than their course book in their target language. Especially when reading in one's target language is such a big help if one really wants to become proficient in the language. You get so much exposure to natural sentences, grammar usage and subconsciously start getting a feel of what's right and wrong in your own usage of the language. It also just helps a lot in real life when you encounter written text.

Is this just part of the broader trend that people nowadays are less inclined to read long-form books and content? That they expect to magically become fluent in a language after finishing every course book? What do you think?
