When I was at school offending the ‘slow kids’ was considered an essential part of the educational process, this is an age when left handed writers were forced to use their right hand and then get berated for having bad hand writing.
Being guilty of being slow, thick, stupid, useless, disruptive condemned you to a life of misery, bullying, parental pressure, abuse and isolation, but who in the school system gave a toss because education was always devised to get the top 10% of the academically able into university, the kids of the middle classes into technical college and the scum into the factories.
Today children who have learning difficulties at least have some support system within the educational establishment giving them a slim chance at progressing educationally.
