Nice article. Never really took the Wizard of OZ story seriously when I was a kid. It was entertainment, period. Interesting perspective on the allegory.
I disagree with the circular happiness thing though. Sure we are never happy all of the time. To be happy all of the time, we need the perfect spouse, perfect children, perfect colleagues, perfect office, perfect neighbors, perfect street, perfect law enforcement, the list goes on and on, but I guess my drift is clear. Most importantly, we need a perfect self, another ingredient that likely does not exist.
If we do not focus on how perfect our situations are in order to be happy, we still may find we need to make the journey to OZ because OZ represents actualization of objectives. If objectives matter and create happiness, while actualization of objectives can create challenges for happiness, we again revert to not allowing happiness be determined by the extent to which our new situation is perfect. In this sense, whether our new place is HOME or OZ, the important thing is we are progressing towards objectives that are core components of our quest for self actualization.
People who have lived in hostile environments can testify to the fact that sometimes a change in location —be it a job, geographical location, or home environment etc. can have a material impact on happiness.
In the sense that ultimately it is our attitudes — wisdom, strength etc. that determine our responses to challenges, however, the article is on point.
