There has always been ADHD around. When my normative group were kids, we climbed trees, played Indian and cowboys and had a lot of outdoor fun. There were some kid or two who was more risky or over the edge, but hey, we had fun.
Today, looking back, I would consider some of my childhood friends to have ADHD or some kind of other diagnose.
Yesterday, these ADHD-kids, was not a great deal. There were also a lot of local jobs and other opportunities as well that didn’t demanded a high education.
Now kids don’t play outdoor and it’s easier to single out the ones with ADHD. Further more people have moved to the cities and there is a greater pressure to study. Today it’s hard to find a decent job for a supporter of a family without a good education.
Hence, without a diagnose, these kids would not stand a chance. They need all the help, support and understanding they could get.
