What Obama’s Historic Visit to Cuba Really Means for U.S. Businesses
The president and Raúl Castro have very different visions for what Cuba could be. · Fortune

Nearly a dozen American corporate heavyweights -- including Xerox CEO Ursula Burns, PayPal CEO Daniel Schulman, Marriott CEO Arne Sorenson President and Airbnb CEO Brian Chesky-- went to Cuba this week to attend an "Entrepreneurship and Opportunity Event" along with President Obama. Top executives from JetBlue , MasterCard , Pfizer and others have already made the trip.

Comparing those lists and the lightweight reality of Cuba's economy, one has to wonder about the excitement. Cuba's economy in 2013 was $77.15 billion, with a total population of around 11.3 million, making an average of $25 a month. Even with the most welcoming investment environment -- and Cuba's is far from that -- the market potential is limited. So what's going on?

The fact that Cuba has been off limits for more than 50 years gives it an undeniable coolness factor. Fidel Castro, brilliant for all of his misdeeds, played the coolness for all it was worth. Starting in the late 1990s, he and his top aides began wooing American farm bureau delegations to pitch the potential of Cuba's untapped market. Tom Donohue, the long-time head of the US Chamber of Commerce, has been a regularly feted visitor -- Castro spent hours talking with him -- and the Chamber became an outspoken champion for ending the embargo. (In full disclosure, I keep a photo in my living room from my own late-night interview with Castro from 1985.)

Those visits were the start of a shift in political attitudes that made it comparatively easy here when Obama and Raul Castro announced in December 2014 that they would be restoring diplomatic relations. While the embargo is still in place (only Congress can lift it and this one is unlikely to give Obama the satisfaction), free trade Republicans are eagerly visiting Havana. In June, Republican Senators Pat Roberts of Kansas, Susan Collins of Maine and Arizona's Jeff Flake (Flake flew to Havana again this week, this time on Air Force One) made the trip. Arkansas Governor Asa Hutchinson and Texas Governor Greg Abbott, who regularly touts his disdain for President Obama, have led delegations of agricultural and business leaders to Cuba.

Coolness is not all that Cuba has to offer, which is a good thing for them because that will fade. It also has a highly literate population, proximity to the US, great tourist potential (although too few nice hotels). And it has consumers, long cut off from the US market, who find American products cool. Cuba needs everything: food, home building products, high tech--assuming it can figure out how to pay.
