I like the idea, but I feel as if this line of argument is overused and becoming ineffective. Yes, we know the wage gap is the problem. We can cite a variety of sources stating that it is a problem, but ultimately, we need to work towards a solution.
Your message centers around the idea that the government should legally prohibit the wage gap. However, this is a fine line to tread. Once you start mandating equalized wages, you are violating some of the freedoms and liberties of corporations. How do you determine when someone is being underpayed due to gender as opposed to underperformance or a lesser degree of skill. There is no law that can solve the problem of the wage gap without addressing these issues. Restating the problem helps, but is ultimately not what we need right now. Instead, I think we need to suggest specific courses of action, instead of vague moral and legal ideals.
