So maybe audio engineers have the lowest divorce rates because they make good money and are quite concerned about fidelity? (This is my bad pun for the day).

Some regard those as symptomatic of other problems or strongly correlate with other issues e.g. lack of restraint, cultural entitlement, issues with inhibition, poor math skills, societal definition and acceptance of "infidelity", addictions.

Infidelity and money issues are reasons for divorce in the same way that clouds are the reason it rains.

I feel a more valuable explanation would go deeper - into the underlying system that creates the result. In the case of rain, we call it the weather cycle.

Source?
