I think a lot of stuff related to depression and ADHD is environmental too. Instead of fixing or helping just drug everyone is the plan. If you're sick of the cold winter, hate your job, etc don't think pills is the answer, should try to move somewhere warmer with a better job.
Then kids not paying attention in school, maybe it's boring or they feel it's useless to them so forcing them to do what they don't want, instead of tailoring their education instead it's one size fit's all. Plus teachers recommend getting kids checked, because then you are labeled as disabled and the school gets extra funding to go into the teachers pension program.
There's someone I know who was told their kid didn't have ADHD, so shopped around and went to another doctor, and then eventually went to another doctor. Kinda like the whole antibiotics resistance thing, people expect if they have a cold that the doctor will give them pills even if it isn't going to really help. Seems like doctors in general just love drugging people, instead of fixing a symptom at the root of the cause drug them and then drug them more for the side effects to cover them up. It'd be like taking your car to the mechanic for a check engine light, and instead of checking the OBD codes and stuff they just unplug the check engine light.
I think a lot of psychiatry is just a form of massive insurance fraud, there's a nonprofit organization that makes documentaries called CCHR. However CCHR is founded by the church of scientology which I know many not a fan of but I think they have some good information. I really wish CCHR would disconnect it self from scientology so it could stand on it's own as I really like their message, but I feel a bit of a conflict since it's related to scientology which is an entire topic on it's own, I guess you have to pay thousands just to level up and all these other horror stories about scientology.
I think drugging children is also a form child abuse, and destroying childhood creativity. Probably if they pushed this stuff when Albert Einstein, Steve Jobs or other successful startup founders were children, who knows if they'd be as successful as they ended up being. One of the pills pushed ended up making males grow large breasts too. Then there's reports another drug can cause brain damage too along with heart conditions(which usually you think it happens in older people but young people can have heart attacks too on this crap). They even want to drug 3 and 5 year olds too. If I was in power, I'd have these drug makers and so called doctors imprisoned for life. Also diet and exercise some believe also helps, add these GMOs and other chemicals in the food, artificial sweeteners can mess with dopamine receptors, etc. So I think I see the larger picture, but many just want a pill and then go back to watching TV or smoking instead of trying to improve their families healthy lifestyle. Kinda like how parents don't even try to teach their children, they just send them to school. Lazy parenting is also part of the problem.
But I guess not a one solution fits all, some people say the pills and stuff helped them. I think counselors could be valuable too, maybe even help you see things from another prospective but some insurance companies won't pay for a counselor unless you also are on drugs. Some people don't even feel like anyone cares about them either, so I think having someone to listen and who seems on your side with issues is also a positive, but I know some counselors want to record your sessions so I find that kinda creepy also as feels less private so you could be less open about things.
