Autism is a proven profit-making industry. Everything in autism space costs money; not just average money but real $$$$$$. It's profit with almost no accountability. If an autistic does not progress, it because they were not going to show progress anyway, you are too old, it's too late, so don't deserve solutions for your challenges or opportunities for your strengths.
Autism is also a career-making industry, with books published, speeches of fancy words at conferences. We are surrounded by money-making "autism-expert-celebrities" though no one still has a clue.
