Dyslexia is the most commonly known learning difference. I say learning difference, because calling Dyslexia a disability is just a point of view.
Having Dyslexia does not mean that something is wrong with you.
There is a lot of value placed on reading and writing skills, and it’s hard to achieve academically without these. Since academic jobs are often the most valued by society and therefore more highly paid, academic skills are what schools push children to learn.
People with learning differences are a (not very small) minority. We have to adapt to a world that’s been set out for people who learn, think and see and hear the world in a slightly different way. No wonder school can be hard. Maybe some dyslexic people can’t spell worth carp, but there’s more to life than perfect reading and writing skills, although some dyslexic people can be very good writers.
In a reversed world, where at schools, the focus would be to learn practical and creative skills such as art, music, gardening, construction, and joinery, “academic” people might be the ones feeling at a disadvantage.
