Those things are annoying and upsetting to deal with but aren't the root cause of unhappiness. I believe it is the lack of a sense of purpose that is the main culprit, and I believe this drives much of the modern malaise as the traditional sources of purpose: religion, family, survival, etc disappear. A lot of people here seem to find purpose in building great technologies, and they generally seem happy despite working (sometimes) crazy hours.
