We spend far more than any other nation yet have mediocre to less than average outcomes compared to other developed countries.  We have the highest rates of obesity (outside island nations) and higher rates of chronic disease than other developed countries.

Sedentary jobs, long hours, minimal attention to diet due to time constraints, poor sleep and stress are all major contributors to poor health.

We commonly mistake pleasure for happiness. 

1.  The sedentary unhealthy lifestyle described above in answer to Q#2 above.

2.  Climate change, endocrine disruptors, pollution and other environmental toxins, and species extinction all adversely affect human health.

3.  Mindless consumerism in pursuit of convenience also robs people of opportunities for consuming a healthy diet, exercising, spending time outdoors, etc. 

4.  Mindless consumerism creates dependence on employers – and thereby ties you to work obligations – thus as workers instead of working for a good or service for the benefit of society you work for money… the result is addictive processed foods among other products designed to sell rather than to improve well-being.

Teach people how to overcome consumerism and work towards becoming financially independent.

Providing a beneficial good or service for humanity then displaces the dollar as the end goal for work.  Human welfare can finally take its rightful place as the reason for work.
