It takes a lot of work to be a parent and also monitor all that media consumption/stop all ads. The “average person” isn’t as tech savvy as most of us here and that stuff just doesn’t come as easily to them.
For instance I am very comfortable letting my kids play video games. I play a lot myself, I can make good judgments about what is appropriate for them, what is an appropriate amount of time to play, what is good/bad behavior when playing, what systems are a good choice or if online access (if any) is appropriate. I barely need to think about these things, but for some people this is an incredibly time-consuming, intimidating task.
Is it not ok that parents that spend more time and effort with their kids have better outcomes than parents that spend less time? I’d rather that than have the nanny state regulate everything bad for kids out of existence; we already know what kind of civil rights violations politicians try to justify with children.
