Karl Marx recommended the abolition of marriage in his Communist Manifesto, stating it would naturally bring with it the dissolution of the system of free love, which he called public and private prostitution. In other words, Marx thought that marriage was nothing but a form of "private prostitution." Inspired by such teachings, in the 1980s, the Australian Union of Students issued a Policy Statement arguing that "prostitution takes many forms and is not only the exchange of money for sex … Prostitution in marriage is the transaction of sex in return for love, security, and housekeeping."
