One of the ways that traditional marriage has advanced society is the delicate balance between a wife supporting her husband almost unconditionally and her motivating him to be more successful.
A demanding wife who does not support her husband leads to feelings of resentment and even hatred between the both of them. It is the root of the trope of the "imprisoned" husband.
Men are more often than not content with less. Many bachelors will have sparse furnishings and live well within their means (when not foolishly attempting to impress women for marriage or sex).
When married husbands want to make their wives happy while also not overly exhausting themselves. Due to the pervasive nature of social media and modern entertainment and the ease of access to loans an unreal expectation of what constitutes as "success" has been fostered among many modern women (and even some men).
This has led many to financial and marital ruin. The husbands have underperformed to the wives expectations of success. This leads to arguments over financial stresses which eventually turn into emotional detachment and in many cases infidelity.
