Marriage promotes a better way to raise children  Marriage promotes raising children as part of a monogamous couple. Without marriage, the frequency of single parent families would rise. Statistically, children who come from single parent families are more likely to live under the poverty line, more likely to be convicted of a criminal offence, more likely to become ill, less likely to complete every level of education and more likely to grow up to have low incomes themselves. (O’Neill 2002) Clearly then, marriage provides a lot of goods to children of married families, thus it provides goods in modern society and therefore cannot be outdated.
