That's a "proud" move of saying: "we have more than what we need." Fidel Castro used to be the same. That's why he sent a lot of doctors to Venezuela and other areas. He wanted to say his revolution made people more educated, so he had so many professionals that he could export them. Unfortunately, people got tired of his game because under this export doctor theory, the doctors were not getting paid, but his government was getting compensated. Then wise Castro will give the doctors 10 pesos cubanos monthly for their salary. So the last Cuban generation decided not to be professionals and not to work for the government. Not a good decision because we can see in Facebook they dont know how to spell and their education is suffering to be as before. Venezuela, there are two choices: overthrow the government or leave the country.
