There aren’t many Dawoon Kangs in Silicon Valley. She’s an American-educated Korean immigrant who founded a company there with her two sisters. Together they run the popular dating app, Coffee Meets Bagel. Their success offers a vivid example of why America should strive to retain the talented foreigners who go there to study.

It turns out that’s not something Donald Trump and his senior counselor Steve Bannon agree on. Late last year, Bannon invited Trump on to his radio show, Breitbart News Daily. The men spoke for 20 minutes about trade and immigration, but seemed to part ways on the topic of highly educated and skilled foreign workers in the tech world.

Trump argued for keeping Ivy League-educated foreigners in the US. “We throw them out of the country, and they can’t get back in. I think that’s terrible,” said Trump. “We have to keep our talented people in this country.”

Bannon responded by suggesting that there are too many foreign executives in Silicon Valley. “When two-thirds or three-quarters of the CEOs in Silicon Valley are from South Asia or Asia, I think,” Bannon said. “A country is more than an economy. We’re a civic society.”

Bannon’s data is actually incorrect. But beyond that, Kang and her company represent a perfect example of why Trump’s right—and his advisor is wrong—about the value of diversity to business and the US economy, as our video above shows.
