I'll try to do this very quickly.
The contribution of NGOs and volunteers and church groups is phenomenal, but at the end of the day, given the level of this crisis, you need a health care system. You don't fund ministries of health through charitable dollars. You fund ministries of health through tax dollars, and until those countries in the global south can generate their own resources from taxes, from royalties, or from other sources, we know that they're absolutely dependent on international aid playing a critical role in strengthening the health care systems we need.
