EPA/Ledbetter Act only for "trial lawyers

According to one labor economist, women in every state make a fraction of what males do. There are many causes but the bottom line remains the same. Utah (55¢/$1) tops the list for greatest disparity, followed by Wyoming (56¢/$1) and Louisiana (59¢/$1). State chart here. GOP senator Marco Rubio dismisses the Lilly Ledbetter Act as benefiting only trial lawyers. Now there are often explanations for pay disparity, and under the Equal Pay Act an employer need only prove there is a factor other than sex causing the disparity. Note, it is the employer's burden to do so one the claimant establishes a pay differential in circumstances where a female performs a job requiring the same skill, effort and responsibility, yet is paid less than males.
