No. We have industry-voluntary schemes such as PEGI ratings, and most products have kid-friendly modes. Spotify, Netflix, YouTube, Disney Plus, Amazon Prime all have kid-specific modes, for example. They're selling to parents, and that's what parents want, so that's what they get.
You're right that governments are needed to make regulations, but not that regulations are needed.
Sometimes what's good for society takes precedence over what people want.
And happily your examples are nothing to do with the call for regulations on the topic of having kid-safe versions of content production, so I feel encouraged.
It's called parenting
> It is much easier to set a limit on a device that is cold and inhuman and can't be pleaded with for more screen time than it is to try and manually enforce such a limit.
If you don't want to do parenting, then you can also block access to netflix (or from the tv or whatever) at your router.
Either way it's a symptom of parents outsourcing parenting, because the culture in both countries is for parents to work 120 hours a week.
