What great changes have not been ambitious?

If you want to lift up an economy in Africa, you basically start with the women.

You can have the best vaccines for a woman or her child, but if you can't get her to come and get them then they won't work.

Contraceptives unlock one of the most dormant, but potentially powerful assets in development: women as decision-makers. When women have the power to make choices about their families, they tend to decide precisely what demographers, economists, and development experts recommend. They invest in the long-term human capital of their families.

Vaccines are a miracle cure. Eight out of 10 children are getting vaccines.

Abortion has become a very politicised issue that I think countries have to work out themselves. In a lot of countries, people can't even yet agree on what their laws should be.

If you don't invest in the woman, empower her, give her the things she needs to lift her family up, you're just not going to make the progress that you want to make. But if you put her at the centre, you can change a lot for that family, and it has ripple effects through the economy.
