Having been covered a good deal of the wealth across my life, I disagree. (Although it is possible of course that I was just happier when I was younger—poverty being beside the point.)
if you spend time traveling (I have, significant time - can't imagine a different life) you will unmistakably conclude that happiest people, by far are from the poor(est) countries. it is only "western minds" that think (this is ingrained in societies like USA) wealth and happiness are correlated.
the happiest part of my life was when I had nothing materially (but no debt, just basically at zero, making enough to live paycheck to paycheck)
