Attitude: $90,000 per year isn't likely to generate enough money for this person's retirement, particularly if they encounter major expenses. He should be spending his new free time either developing a side-hustle, a business, or delivering additional value for his employer for which he must insist on additional compensation. I used to be well aware of evidence & case management systems and this person is one decision away from existing software making his perceived job less relevant.
Antiwork: I entered the workforce during a deep recession, and I was a recruiter for infoTech during another recession. I've traveled extensively overseas for work. It will be an employers market eventually, perhaps soon, and the antiwork crowd is going to meet reality head-on when it happens. Nothing wrong with ditching bad employers & developing side-hustles. There is something wrong with demonizing work. Part (by no means all) of the growth one sees abroad is due to acceptance and often positive attitudes about work, with less emphasis on "fairness". Life isn't even close to fair and some societies and people understand how to work with that better than others do.
Let the downvoting and flaming begin (sadly).
