I dont' think its status as much as a decent basic necessitites thing along with security. If you have the money to live in a decent, clean, healthy environment with food and knowing health needs or such will be met and then further know that will be the case until you die. Then its much easier to be happy. I get the studies though but im always suspect. Like how much of the U is specific to a sorta point in time and is it eroding for people getting to those ages.
