Why has dyslexia suddenly become so prevalent in society?
Dyslexia has not become more prevalent, it is just that our society has changed to make it harder for dyslexics to operate. As our society becomes more literate, dyslexics increasingly have problems dealing with education and work. Also, we now know more about dyslexia and how to diagnose it, so many more people than previously are now being shown to be dyslexic.
