The share of Americans ages 25-34 who are married dropped 13 percentage points from 2000 to 2014. A new book by sociologist Mark Regnerus blames this declining rate on how easy it is for men to get off.
Regnerus calls it “cheap sex,” an economic term meant to describe sex that has very little cost in terms of time or emotional investment, giving it little value.
Regnerus bases his ideas, in part, on the work of British social theorist Anthony Giddens, who argued that the pill isolated sex from marriage and children. Add online pornography and dating sites to the mix and you don’t even need relationships.
