There is some research about "happyness" that started around 1970, two difference scientists asked more or less similar question since then: what you did in your day, and how happy you felt.
In 1970 women used to claim to be happier than men, there was a very large gap there.
Currently the gap is smaller, but reversed (men are happier instead), also both men and women are unhappier than in 1970s.
Regarding workload, women are working now (summing home chores and outside work) much more than 1970, men are also working more, but one thing that the researcher was noted, is that the time specifically dusting the house decreased a lot, since there is no major invention in that field since 1970s, he had the conclusion that maybe the source of unhappyness is that people don't have time even to keep their home clean, and are living in homes that are dirtier than they were in 1970.
Now I need to figure where was those articles (there are two of them with published data), I frankly don't remember :( (I stumbled on them on a night of random reading on internet)
* The US economy, at least for part of the populace, is pretty crappy; working three jobs, money worries, the financial crisis, it all adds up. * The internet; more (negative) news from all over the world, telling people how terrible it all is. At the same time, "Facebook Envy", people getting told how bad their life is in comparison to their facebook friends (which is skewed because a lot of people only put the good stuff on there). * People are dicks.
I've had no experience with anyone I know of committing suicide, but I am not seeing how to evaluate whether it is or isn't socially acceptable.
On the other end of the scale we can talk about "Dying with dignity", "Not being a burden to loved ones", "finally at peace", "being in a better place".
When more people hold the later views then it is more acceptable in society for someone to commit suicide because they don't feel that they are hurting others as much/aren't as evil for doing it (not that I believe they're at all evil I used that wording as those considering suicide may be self loathing).
You could even make arguments on a case by case basis if you wanted from the heroic last stand to a single parent leaving behind their children. It all comes down to what obligations we feel people have to stay alive.
