As anyone who does relationship or health counseling can tell you, they're very closely linked. Financial problems destroy more marriages than any other single issue, and the stress of a bankruptcy is comparable to that of the death of a family member. Health and wealth are also closely linked. So it's not as easy to separate these issues as you might think.
You are right - and that is exactly I'm trying to say.
People do make that mistake and organize their life in such way to connect wealth with relationship/health (maybe based on society, how they are raised, I don't know). And then their relationship suffers when one of partners loses a job or anything bad happens in the material world. It should be other way around: relationship should be stronger when resources get scare.
And I agree it is very hard to separate these issues... I guess one needs to be "indoctrinated" as a child.
I guess I just don't think that's possible. Yes, we could be better about separating these things to some extent, but not completely. Losing everything you own is incredibly stressful, and stress is damaging to health and relationships, period. Similarly, the dissolution of a marriage always results in a net decrease in wealth for the combined parties, at least in the short term. And battling health issues is damaging to both relationships and your financial situation, on average. This is just human nature. "Whatever doesn't kill you makes you stronger", but sadly, a lot of things actually do kill you (or your health, 401k, marriage, etc).
Furthermore, a big part of the correlation you see between relationships, health, and wealth are due to very similar "life management" skillsets being required for them all. It's obviously not perfect correlation, but it's there for a reason.
