Dilip Ratha knows how hard it is to work abroad and send money home. Why? Because he had to go through the same hoops when he was a migrant.

It's the inconvenience and the cost, the World Bank's head of KNOMAD and lead economist says during a livestream conversation on closing the global digital gap hosted by GZERO in partnership with Visa.

Still, Ratha points out, these flows are a lifeline for millions of poor families around the world. And they keep the lights on in remittance-dependent economies like El Salvador or Lebanon.
