TBH Chinese are still very hands on helicopter parents, even when they work ass off. The issue is you can be strict and controlling and still lose to corporations who spend billions to engineer addictive products. Which at minimum takes disproportionate resources / attention to mitigate. Hypothetically this is where parents complain to state to regulation since ostensibly corporations are suppose to cede control to state. Plus don't have to be the badcop trying to enforce screentime when state takes that choice away. Also plenty of parents who cede control to corporations and allow products to baby sit their kids by giving kids access to adult ID to circuvent restrictions. I feel like US voters are pessimistic their gov can shape corporations in some realms. Like loot box regulations for youth feels like it shouldn't be that difficult to pass.
