Winnie Byanyima, executive director of Oxfam International, said those in authority needed to reevaluate their systems in order to address poverty and tackle inequality.
"Governments must now deliver real change by ensuring corporations and wealthy individuals pay their fair share of tax and investing this money in free healthcare and education that meets the needs of everyone – including women and girls whose needs are so often overlooked," she said in a press release on Monday.
"The size of your bank account should not dictate how many years your children spend in school, or how long you live, yet this is the reality in too many countries across the globe. While corporations and the super-rich enjoy low tax bills, millions of girls are denied a decent education and women are dying for lack of maternity care."
Around 10,000 people die every day because they cannot access affordable healthcare, according to Oxfam. Children in developing countries are twice as likely to die before the age of five if they come from a poor family, while rich children spend twice as long in education.
