According to calculations from the Equal Payback Project, American women are owed $29,811,746,430,000 (that's U.S. dollars, also known as U.S. golden dollars with Sacagawea on them) due to the wage gap.
Working female Sarah Silverman is fund-raising for this exact amount. She promises that if this fund-raising goal is met, each woman in America will receive a check. If not, the money will go the National Women's Law Center, which advocates for legal and structural changes to support professional women. They're only trillions dollars away from removing this gap off the list of gaps facing women today.
