It's in France and I guess everywhere else. Students can cheat for free and no longer need to do anything, why would they study anymore?
I've also seen a few young engineers using ChatGPT to do their job because it's easier than working. When I told them their code was bad (with mentoring and help, I'm not an asshole), they used another prompt that changed their whole code but it was still full of bugs.
We're doomed.
In France you cannot fail a middle or high school class anymore. The official explanation is that it hurts the kids' feelings. The teachers' explanation is that too many people would fail.
