This video from Vox begins with the often cited statistic that women make 79 cents for every dollar that men make. That statistic is correct, but there is a lot more to it.

One element of the problem is that women are concentrated in lower-paying jobs. Another element is that men tend to get slightly higher paying jobs immediately.

However, this video focuses on the need for flexibility. It describes that the wage gap widens as women get older in their 20s and 30s but then starts to shrink. This is largely because women still take on a larger percentage of childrearing tasks than men, even if both parents are working full time. Jobs which are more flexible have lower wage gaps than jobs that have set hours.

The video ends with a simple idea to work towards shrinking the wage gap: “There are lots of jobs where hours can be more flexible than they are now. The more we can make that work, the more the wage gap will shrink.”
