As someone stuck in the lower class almost unable to work and any work I do is very distressing because I'm someone who is chronically disabled with chronic debilitating pain and an array of other problems that are no fault of my own: Ain't this some bullshit. It sure is easy for the rich to say "just be happy", "just follow your goals" etc. It's so easy for people with opportunities to say that, is it any wonder the richest people I know are also the happiest.. I wouldn't be surprised if the people in this study are in higher positions than the rest and have less stress and demands put on them in their daily lives.
