Well, fewer than what? I'd wager the median person reads 0 (or perhaps 1) books per year, where a book means something with more than 100 pages and at least 90% of those pages filled with text and read means read at least 90% of the words printed. To most people reading is like exercising, dieting, studying etc. They want to want to do it but don't want to do it.

You must live in a bubble if you think normal people read too many books.
