This reminds me of Scott's post over at Slate Star Codex about Moloch [0]. The issue here isn't so much about _realizing_ the futility in pegging one's happiness to one's profitability. The issue is that for any one person to forgo this standard (s)he would be required to give up the status conferred on being a profit-generating American. This is against his/her interest. Thus, most Americans would rather work harder and be more productive/profitable and maintain their status, than attempt to achieve a more authentic happiness, and risk being perceived as a failure by others. To actually alter this standard would require changing the cultural norms around status and profitability either from the top-down, or from outside entirely.
