Really? Last I read the correlation breaks above a certain threshold, roughly that of "I don't need to worry about food or bills".

It's worth noting that while the curve flattens above a threshold, it doesn't level off completely at that threshold, there is still a positive correlation, just a smaller one.

No, that study was constantly misreported on. There's a nice correlation all the way up.

And that threshold would set someone in among richest 1 percent in the world.

And when is that exactly? It definitely isn't making (unadjusted for inflation) the $70k that study suggests.

People are happy when they are secure and unhappy when they are insecure. Who can you name is secure in all of their physical, social, mental, spiritual, etc needs right now?
