现在时髦追求自我最大快乐.25-34 who are married dropped 13% from 2000 to 2014

Thanks to cheap sex, marriage may be doomed.

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.

"Men have figured risk out and have been left with exactly zero options available to them to mitigate it  Many have simply decided not to go down that road because the outcome is completely out of their control."
