>Overall peoples happiness go up and down.

Not by much. I seem to remember some research that compared lottery winners to double amputees. Within a short period both groups had reverted to similar levels of happiness.

>I could go on ... the inequality and accumulation of power is threatening to make most of us all worst off and it is not because we got spoiled by hedonistic treadmill.

There isn't much individuals can do about that outside of polling day. What they can do though is start comparing their lives to their grandparents rather than the Kardashians.
