Drugs and shit aside we could just decide to change how we as a society measure quality of life and national strength. Like with Nepal, instead of measuring national strength in part on Gross Domestic Product, we look at it from the angle of Gross Domestic Happiness. So then we start voting in leaders who make domestic happiness a priority. GDP could still be used, but what's the use of money when no one's happy about it?

This'd be a huge culture clash and a massive war against the individualistic life-style that the western world is built on vs the hollistic community-oriented life-style of Nepal, India, and East-Asia. We'd have to stop teaching ourselves to orient our lives according to self-made, individual success as the primary focus of a good life and shift it to being a part of and maintaining healthy relationships with everyone around us on a personal relationship and community level. An entire shift in our way of thinking.
