In the marriage economy, through the complementarity between men and women, we can make full use of resources, realize economies of scale and obtain economies of scale. Men and women with different professional advantages, abilities and incomes can maximize their benefits through marriage, which is a complementary and win-win scheme.
For example, men are outside and women are inside, or women are outside and men are inside, which is more efficient. Complementary advantages and optimized combination can increase remuneration, which is one of the reasons why the economic situation of marriage and family is generally better than that of single aristocrats.
The purpose of marriage is to get the greatest benefit from marriage. If the income from marriage exceeds the income from being single, then people will choose to get married, otherwise they will be more willing to be single.
