It’s my pet theory that kids these days have so many gadgets and doo-dads to entertain them that they are hardly ever really bored. Many more kids have access to their own mobile phone (probably even with Internet access) now than in 2000. Combine that with the game consoles and other devices, and it’s no longer necessary to go hang out on a street corner to interact with each other.
Most kids who got in trouble back then got in trouble because they all hung out in a group, being bored together, and gave in to the worst idea that one of them had. It’s a lot harder to get in that type of trouble when they are all talking to each other in a group chat from their bedrooms, or while playing a video game.
