Melinda Gates has committed to spending $1 billion over the next 10 years to promote gender equality in the U.S.

Gates, the wife of businessman Bill Gates, announced her commitment to expanding womens power and influence in the United States in an essay for Time magazine published Wednesday morning. The philanthropist believes the commitment is only a small fraction of whats needed to right gender inequality in the country, she wrote.

I want to see more women in the position to make decisions, control resources, and shape policies and perspectives, she wrote. I believe that womens potential is worth investing in and the people and organizations working to improve womens lives are, too.

Using her company Pivotal Ventures, Gates will funnel resources into companies that are actively trying to uplift women in business, politics and more. Her three-pronged approach includes dismantling the barriers to womens professional advancement such as caregiving responsibilities and sexual harassment at work. Additionally, Gates plans to help fast-track the careers of women working in technology, media and public office, because, she writes, these industries were designed for and created by men. Lastly, Gates will fund research and data on gender inequality in several sectors.

I hope the financial commitment Im making today is seen as both a vote of confidence in the experts and advocates who are already working on these issues and an invitation for others to join the cause and make commitments of their own, Gates wrote. Equality cant wait, and no one in a position to act should either.
