This depends on the individual character traits of each person, according to my observations, this happens differently in each family, but if the family is engaged in one common business, have a common budget, and strive to achieve common goals, then their financial management will be more harmonious, without any significant differences. If this is not the case and only one family member provides for the family, then the situation may be different, the one who earns may consider that he is more economical, because he values his work more.
Agree with your opinion, actually the issue of being thrifty and not thrifty depends on each person, not a matter of gender. Because many men are more frugal than women who are more wasteful and cannot control their spending. Financial skills are a skill that needs to be mastered by all groups, both men and women.
In conclusion, financial success depends on previous generations. In this case his parents.
1. If parents are good at managing money, their children can achieve good financial success
2. If there are parents who cannot manage money, then those parents will make their children a wasteful generation.
In essence, the man is the head of the family in the household, he is the one who earns money and his partner is the one who manages all the finances so that the family remains financially stable.
