Not really important to change the ways of (third world) development since no conclusive investigation has successfully and recognisably shown this and probably it isn't possible yet, but here's a thought: Isn't the world making a mistake by (merely) focussing on economic growth and freedom in that way that we will bring certain population in the same unhappy state as a lot of (if not áll) the current more economic developed and "civilized" world in their noble goals ? By this I mean to say that you can't possibly deny that the more advanced countries of today are also the countries where more unhappiness to depressiveness occur, which on itself is an indication of the average total happiness or mental state. Indicators that are shown in several studies to be more common in these countries: more suicides more therapy (e.g. in the UK today there is such a % of the population taking Prozac that it can be found back in the tap water!) loneliness, exclusion and so
Just stuff, you know.
