That's quite a naively false and shallow theory, Luis.
Especially when it comes from you.
Is "protectionism and nativism unbound" what gave Castro to Cuba?
As I recall, the United States didn't ban trade with Cuba until AFTER Castro came to power.
Prior to that, we enjoyed the importation of many Cuban products, most notably cigars, sugar and rum.
And many American products were exported to Cuba, such as many of the automobiles that they're still driving.
And American tourists regularly visited Havana for the swingin' nightlife.
But then, I'm hardly qualified to lecture you about conditions in pre-Castro Cuba.
You of all people should know that we didn't suspend trade with Cuba until AFTER Castro came to power.
Communism is a cancer that festers in the despair and poverty of a people when a nation's wealth and political power are concentrated and controlled by an elite, upper crust. It spreads through the very conditions that you're attempting to create with the economic erosion of the American Middle Class.
Absolutely Willie, Castro did not promise to nationalize industry to get into power, he did the exact opposite.
There were no economic issues in Cuba, other than in your Marxist theories...lawyers (Fidel), and doctors (Che), did not rise up in the best interest of the working class, they did it in their own best interest.
Fidel Castro was a known communist since the 1940's Willie.
Of course, you will bad mouth America, and embrace the communist revisionist lie that American industry was at fault for abusing Cuba's proletariat (trying to use words you're familiar with here), and that this "abuse" gave rise to Castro's revolution.
You're just another leftist fool romanticizing Castro.
