Exactly. Charge the parents for neglecting their responsibility.
That being said; we more need campaigns to educate parents on “how-to”. Often parents don’t create restricted user accounts for the OS. A friend of mine wanted to keep their kids access to th computer more restricted and asked for my help. So I created 2 restricted accounts and gave her control
if they wanted something installed they had to ask her to install it I set it up so she could view browsing logs for Internet activity
Only issue she had was her oldest knows her so well he could figure out her password within 15m
So I told her let me set the password and give it to her. I set the password as “dark4321” with a hint of Grandmother’s birthday it kept him out the admin account for several months, until he overheard her talking to her sister on the phone and she mistakenly said out loud "No he still hasn’t figure out that the pwird is “dark4321”.
He spent a lot of extra time with his grandmother trying to figure it out. 
Everything I setup was part of windows no 3rdparty programs.
