In 2056 A.D., due to a serious cosmic radiation, the ratio of male to female fertility on earth was seriously imbalanced, from 1:1 before radiation. 05 quickly changed to 1:20, that is, every time a boy is born, there are 20 girls born, and the proportion is still rising, the scientific community is at a loss for this! As a result, there are many social problems, first of all, employment. Due to the limited work suitable for women, a large number of women are facing unemployment. Secondly, the marriage problem. Due to the imbalance of the ratio of men and women, a large number of unmarried women are produced on the basis of monogamy, which causes social instability. In response, governments have taken a lot of measures, such as abolishing monogamy, but few men are willing to marry 20 wives. Despite a lot of measures taken by governments, women’s employment and marriage are still the most difficult problems in the world. Women’s organizations continue to put pressure on the government. No matter what measures the government uses, as long as the employment and marriage rates of women can be improved, they can win a large number of votes. In this situation, governments have adopted a lot of methods that were previously unimaginable.
