It's a bad combination of a lot of bad things for things to go this way. Imo here's a pretty accurate meme that explains part of the contribution...

When people accidentally pushed their kids to a place in which they can't even express themselves, what do they do? And I doubt that many understand the implications. Yes, put the blame on the internet, on the school, on the phones, computers, whatever that seems to cause these statistics, but come on...it's what you get for having better technology, it comes with a price. More sources of bullying and problems, more things for the parents to handle.

I admire the parents that have a 100% clear two-way communication with their kids, that's how things should work...
