Developing countries must also find creative ways to increase government revenue. Even the poorest nations today fund the large majority of essential services like health care and education. But many don’t have the expertise and resources to raise more money through broad-based and effective tax collection.

One effort backed by the U.S., the U.K., Germany and more than 30 other countries will double the technical support to poor countries, helping them increase tax collection and domestic revenues. This minimal cost could significantly strengthen the efficiency, effectiveness and transparency of tax systems in poor countries.

It can be done. Rwanda–through a combination of legislation, stronger administration and more effective taxpayer registration and compliance–increased revenues by about 50% between 2001 and 2013, the Organization for Economic Cooperation and Development found.

This is from Bill Gates, “A New Map of Poverty, a New Approach to International Aid,” Wall Street Journal, April 15, 2016.

You might think that Gates is advocating taxing only wealthier people in poor countries. But the word he uses that shows that he is advocating taxing poor people more is “broad-based.”

And to think that I used to defend this guy.
