To each his own!
Perspective is different from one person to the next. It is always easy to judge someone without having walked a mile in his shoes. Home is what you make it! You can be in paradise or hell depending on your outlook / perspective on life and things...
I agree with u tournesol. If your not happy about your life, you're the only one who can do something about it...
People that are happy, don't generally complain about it! They might be part of a "silent majority"...
