Working a job doesn't fix either of these problems. At least in the US, many people who go bankrupt due to medical issues have health insurance, usually provided by their job. These problems are compounded if your plan was to work, but you can't work due to your medical problems. And while medical or disability insurance can theoretically account for these worst-case scenarios, they can be so costly that they may cause financial problems even if no disaster happens.
Divorce is also a major cause of bankruptcy, even if you're employed.
You're doing exactly what my previous post accused people of doing: gloating about how the author's plan failed, without looking at how plans that fit your worldview don't account for the same life events any better.
