Why Discrimination is Not always the Cause of Wage Disparity

Jumping to conclusions is something people do.  Let's take the case of wage disparity.  I have several acquaintances on social media who like to tout the difference in wage between men and women as an example of sexism and discrimination alive and well.  Now, with a new election coming up, both parties are touting their support for equal pay.  But discrimination is not the cause of wage disparity.  It's genetics.
