I do think social media and advertising plays a huge part in this.
Adverts always show blissfully happy families, in frankly ridiculously enormous houses, with new cars, and angelic children. And although everyone knows they are not real life, I think it drip drip drips into the mind that "this is what everyone's life should be".
For the most part, people post the good part of their lives only - or fabricate tales of how good their lives are - and therefore everyone thinks that all their friends are living wonderful lives, and if their own situation doesn't match up, they feel as though they are failing.
I think "our generation" don't really understand the pressures and influences of social media, because we didn't have any of it. I also think a lot of us are too quick to condemn the "younger generations" because they don't have it as tough as we did and don't behave and react the way that we do/did.
Just because their tough times aren't as bad as our tough times were, doesn't mean they're not valid. No doubt the generation currently being raised by our own sons and daughters will also have their problems, which our offspring will roll their eyes at.
