Not necessarily, happiness (in a meaning of long lasting sense of personal satisfaction) is mainly about meeting the expectations (yours, of your family, peers, etc.). IMHO it primarily depends on to whom you choose to compare yourself. People in isolated environments have less peer competition and much lower expectations as everyone they know about is living the same way. If you and everyone you know expect to die at age 40, then it's merely a fact of life, like dying at 80s is for us. You don't think of it as injustice as you;re not aware of any other way. If you are poor your whole life, just like everyone around you, you still can feel extremely accomplished and successful in life, if you manage to get just a few chickens or a goat or more children or whatever more than your neighbors. It's one of the evils of the Internet that now we all compare ourself with the richest and the most successful people world-wide, and not just from within our local communities as before. I know it makes me unhappy quite often. People who never been in civilization are probably more content with their lives, as what else could they wish for, other then what they already have? Of course, just statistically speaking of the whole population, each individual has it's own ups and downs and unique ways, jealousies and envies and everything...
