We don't police big tobacco very well on making their products more addictive. We seem to be fine with expanding gambling - where I live (not Nevada!) slot machines are everywhere. Nice restaurants even will dedicate corners to slot machines - not just seedy bars. Sports betting apps are all over streaming ads, and their legality is expanding even though when they are legalized in an area the divorce and loan default rates go up measurably.
Why would we regulate big tech if we don't bother with anything else?
The kids are just the latest victim of a long ongoing trend.
I’m pretty sure we do, in fact, ban under 18s from tobacco, alcohol, and real-money gambling.
If that's not enough, in the US we created a federal level agency that oversees 3 things only. Two of those things are alcohol and tobacco. And the third thing isn't even regulated half as much as those two.
Why on earth anyone thinks these things are unregulated is beyond me.
