There are only three black chief executives of Fortune 500 companies, and that has to change, according to a CEO who knows something about breaking down racial barriers to the C-suite.
As CEO of Carnival Corporation, the largest cruise line in the world, Arnold Donald says that diversity is a valuable business strategy.
"For our communities to thrive, for our companies to thrive, we have to proactively engineer diversity of thinking into our companies," Donald said in an interview Thursday with Cheddar. "That's what I'm doing at Carnival, that's what I've done at other places, and the results speak for themselves."
In Donald's five years as chief executive of Carnival, its market cap has increase from $27 billion to $45 billion.
Despite living in the age of data gathering, machine learning, and social-media influencers, Donald said he still believes in Carnival's old-fashioned appeal.
"The most powerful marketing tool is word of mouth," he said. "We have a lot of people who cruise, as I mentioned 83 million passenger cruise days a year, nearly 13 million guests just on our ships, and if you know someone who went on a cruise, and you trust them, they're your most reliable resource."

Apple CEO Tim Cook said Thursday that the majority of iPhones sold in the U.S. in the current fiscal quarter will be sourced from India, while iPads and other devices will come from Vietnam as the company works to avoid the impact of President Trump’s tariffs on its business. Apple’s earnings for the first three months of the year topped Wall Street’s expectations thanks to high demand for its iPhones, and the company said tariffs had a limited effect on the fiscal second quarter’s results. Cook added that for the current quarter, assuming things don’t change, Apple expects to see $900 million added to its costs as a result of the tariffs.
