When ADHD negatively impacts your life, it is time to seek treatment options. Medication can be very effective in most individuals, and both children and adults have a lot of self-doubt tied up into the troubles with executive function that ADHD/ADD bring.
While it is true that modern public school systems, especially how they operate in the United States, was in many ways designed to create obedient factory workers for the industrial revolution. That sufferers of ADHD don't thrive in that environment is a symptom of a greater challenge that individual is facing, simply removing our arcane repressive education system doesn't suddenly fix everything for someone with ADHD. I completely agree with the sentiment that public schools are not looking out for what is in the best interest of the children. A problem that exists for children that don't have ADHD as well. But even in a home school environment, the outcomes for someone with untreated ADHD is not encouraging. Not just academic outcome, but psychological, emotional, and relationship outcomes as well.
