According to the U.S. Census Bureau, as of 2006 only 3.6% of alimony recipients were men. https://en.wikipedia.org/wiki/Alimony#History
Mothers are granted custody in ~80% of cases and are the recipients of 94% of child support dollars paid: https://dalrock.wordpress.com/2011/08/15/latest-u-s-custody-...
Men make up 93% of the current prison population: https://www.bop.gov/about/statistics/statistics_inmate_gende...
Men are assumed to be sexist by default: https://amberskyeforbes.files.wordpress.com/2013/09/1240542_...
Men have no reproductive rights. If a woman decides to cede responsibility for her child, she can abort it or give it up for adoption. If a man decides to cede responsibility for a child, he is labeled a "deadbeat" and on the hook for child support payments anyways.
Only men are required to register for the United States Selective Service.
According to a 2012 CDC study, more men than women suffer from domestic violence and psychological aggression: http://www.saveservices.org/2012/02/cdc-study-more-men-than-...
But when the very first domestic violence shelter for men opened in the US it was panned as a misuse of nonprofit money: http://www.xojane.com/issues/domestic-violence-shelters-for-...
More than double the available scholarships for women than for men: https://www.scholarships.com/financial-aid/college-scholarsh... https://www.scholarships.com/financial-aid/college-scholarsh...
So yeah, there's a pretty clear imbalance of power.
