From a parents perspective, I feel you are incorrect.

Almost every other parent I speak to are well aware of how detrimental screen time is to their kids, and yet often still use devices when they're too tired for much else.

I don't know what you think unemployment looks like, but for most people it's incredibly stressful and not a time when you can just sit on your ass and watch TV all day. The benefits, if you manage to secure them - are barely enough to get by.

Someone who is unemployed, especially if they’re poor, doesn’t suddenly have a lot of free time and headspace. On the contrary, they just got more stressed and pay even less attention since now they have yet another urgent issue weighting on their mind.
