No, but losing the wealthiest nation on the planet as a potential trading partner does mean that you are going to be selling your goods for less than you might be able to otherwise.
Being permanently locked out of the most lucrative deals obviously is going to have an economic impact.
The Cuban state firms don’t produce anything of value. They’re a net recipient of food aid, their tourism industry is anemic and the largest source of dollars and euros. Their medical exports have been called slave labor by the UN.
What could they possibly sell to the US? Even with endless Soviet support in the form of fuel, tractors, and agricultural experts they never produced as much food as the island did before the revolution.
The fact is that what little the government earns from trade they’ve always spent on exporting revolution. Cuban intelligence for example was helping run Venezuela’s SEBIN and secret prisons.
I’m shocked that people on hacker news defend a place that bans the internet, and locks up people for reading banned books.
Additionally, the US embargo limits third parties from trading freely with Cuba in certain ways, and prohibits most Americans from traveling to Cuba. Cuba was a popular destination for American tourists prior to the Revolution.
And I'm not sure I'll continue to reply to this thread. Somehow I find myself repeatedly defending the Cuban system, of which I am not a fan!
