This article is an example of lazy journalism. 

 People in media, just like in sports,  are paid differently for reasons outside of gender.  And since when is Jennifer Lawrence the poster girl for a gender wage gap? She's not making a wage, ladies and gentlemen. .She's a star in her twenties who is getting paid over 10 million per picture and has an agent to negotiate for her, unlike equally talented male actors who toil in obscurity.  These are ridiculous examples of gender wage gap. 
Equal pay for equal work has been a law in this country for many years. 
I am utterly fed up with female journalists who whine about a mythical wage gap and use media and female sports figures to illustrate a non-existent issue.
