Another factor to add in as we search for the mythical "perfect" place is income and war.

A study was done in the recent past that analyzed wars, many of them civil wars, and the conclusion was of about 40 odd conflicts, only two (one was involving modern day Serbia as I recall) involved nations where the per capita income was over $3500. So if you give a person/family a "stake" - a chance or a position, well, you do the math.

In my local County Supervisor race, I was doing some research and one local political point (remember, all politics is local) was that if there was a conflict between party affiliation and a person being a homeowner, the homeowner part of a person usually won out over party affiliation.

The Last Sasquatch should also note that culture is a big factor too. I suspect Thai's are generally more happy than say, Ukrainians, though the latter have a higher income. Some of that is culture or national identity and some of it is not having to live where there is a lot of snow.

Such was noted in the book 'hackers' by steven levy.   If you gave the people who were causing trouble on your computer system a job in the computer center, for most, the behavior stops.

In the US of A, the myth is 'anyone' can be president.  There are a bunch of maxiums about hards work getting one ahead et la.

The reality is - the welfare system places many people in a stakeholder position.  For cheaper than placing them into the prison system.   When the effects of peak oil hit and the welfare system as it exists it trashed, I have little faith in the finding of another 'stakeholder' idea in America.
