alt Hacker NewsYou have a point but as a kid I would definitely spend that much time reading (mostly novels but also newspapers).
I was definitely not present or available when reading.
I think this is all a very complex topic and the desire to find a clearcut simple answer is more damaging than helpful
Between the morning/evening news, a sports game or TV movie, reading the newspaper, and a bit of novel reading, my parents in the 90s were just as physically-available-but-in-their-own-world as somebody scrolling TikTok for 4-5 hours a day. I think the difference is that reading the newspaper isn't literally a dopamine-fueled addiction and turning the page in a novel isn't the psychological equivalent of pulling a slot machine lever.
We have lots of evidence about how harmful it is to have parents that are in the throes of gambling addiction. Folks, it's not good for the children. It's in fact pretty bad, even if they don't gamble away the home equity and the college fund.
