I'm not a fan of the You Tube channels aimed at getting toddlers to demand particular toys. Not at all. However, there are people posting useful information all the time. Like when I wanted to make sure I was putting my sim card into my phone correctly, of course there was a YouTube of it. In fact, there were several.
Well, it's not just do-it-yourself types. There are also professionals giving away their advice, sometimes with the goal of getting you to buy something else, but sometimes just because they want to make the world a better place.
I think this is one example of the latter - a clear, five minute explanation and suggestion on how to help troubled kids at school:

And I clicked on the dude's name and went to his about page. This is what he has to say:
"These are some of my thoughts on life, human development, psychotherapy, traumatic stress, etc. I put them out into the universe with the intention of reaching out to people who need help and want to help others grow in their ability to love and be loved. PLEASE SHARE MY VIDEOS! You don't have to ask permission to use them in your own trainings, but I would love to know that you use them and how you use them so I can feel that the work is making a difference somehow. I am a clinical psychologist, psychotherapist, researcher in psychotherapy and epigenetics, and trainer in traumatic stress. I'm an Assistant Professor in Psychiatry and Director of the Center for Child Trauma and Resilience at the Icahn School of Medicine at Mount Sinai in New York City and work out of Mount Sinai Beth Israel." www.drjacobham.com
