Bill Gates is one of the richest people in the world. So when he doles out advice about how to spend money wisely, it's a good idea to listen.
Gates' latest investment tip? Cutting off aid to other countries could actually worsen the very problems President Donald Trump and other critics are worried about — and have a big economic impact.
The Microsoft co-founder and philanthropist was in Washington, D.C., on March 15, 2018, to discuss international aid projects, including those spearheaded by the Bill and Melinda Gates Foundation. In an interview with C-SPAN, Gates said he disagrees with Trump's "America First" approach but said that he'd try to explain the merits of international aid within Trump's worldview.
