I don't think it's a "sign of the times" thing, I think it's an internet thing. If you made that claim outside IRL today it would be well received by nearly everybody, including people with bad personal experiences (if only because most people prefer to believe that good outcomes are the norm instead of wallowing in pessimism.)
But the internet? The internet is packed with people who focus on the negative, even people who resent their mothers (who may love them and treat them well) because they're so miserable they wish they had never been born.
Always remember that talking to people online doesn't give you a representative sample of what people at large are really like. There's a selection bias in play; people who have problems with "real life" have a tendency to spend more problem online.
