Thanks for sharing your experience. the term "dark chasm lurking just beneath the surface" to describe what total freedom looks like on bad days speaks to me.
I also agree with your assessment of his partner. Keeping up with the Joneses sounds shallow at first, but I think it belies the true human desire to be respected by others. Maybe his partner felt like they weren't "accomplishing much" in life, which doesn't mean a 9-5 per se or an annual income $ per se, but that accomplishments were the best way to get respected by other people.
We're social creatures, so I don't think it's wrong to seek social validation by others. I think when one is single and looking for a partner, what other people think does matter a lot. I think if the author was still committed to not working, finding a partner would be much harder.
