No, my husband comes from a middle-class stable happy enough family. He was self-motivated and built a good enough career and life for himself. But in his childhood, his family also could struggle a bit financially with 3 children, him, his 2 years older sister, and his 2 years younger brother. He knew to have a better life financially he had to try his best at school, college, university, and in his career to achieve what he has achieved Thank God and him.
But if my husband was originally poor, I would still agree to marry him and we would build a well-off life together working on it together and as a team (like we have done). Happy marriage commitment means 'for better for worse, for richer for poorer, in sickness, and in health'.
Some men/women/families can become rich and well off and can become bankrupts making wrong decisions in business/investments and not all families survive after that as well. If someone is rich/well off, it's never a guarantee they will stay like this for life and they could also have financial ups and downs from time to time.
People can be in different life situations because of different circumstances. Their financial success also depends on if their parents/they have good health as well as good mental health, resilience to work/study hard etc. If they had a clear vision and goals for what they wanted to achieve in their life career-wise and financially. Some people can be happy with the bare minimum in life, some need more or much more but often they have to work hard or very hard for it.
Some people can come from dysfunctional poor families that are NOT their personal fault and can build a happy stable minimum middle-class level for themselves and their family and more - higher income level, can become richer) and more well-off and financially more stable and secure than their parents.
A person's upbringing in poverty and their occasionally not-so-happy childhood is not necessarily their own poverty for life.
