They are wrong. Most of those surveys are designed by people with a very clear view of what life should be that doesn't reflect the values of less materialistic societies.
A good example is the corruption index published every year, when the US always comes out as one of the least corrupt countries in the world. We all know for a fact there's tons of corruption in this country, we just decided to legalize most of it. Doesn't mean the US can teach anything to any other country about corruption.
Ok, but you're asking us to trust your opinion, and your opinion on data, coming from a position of being angry about where you live. Whereas most of us choose to live somewhere that makes us happy.
But anyway, I'm sure there are great reasons to discount the corruption studies and the studies of quality of life.
I haven't seen any of them in this thread, though.
