For the doctors whose backup plan was to come to the US, they evidently have nothing binding them to Cuba other than the contract. Why not stop remitting the money to Cuba?
Apparently the Brazilian government is paying Cuba for these doctors, though. Is the Brazilian government indulging in slavery by proxy? And would they go after a doctor who jumped the plantation?
“Would they go after a doctor ho jumped the plantation?”
No, they just have to go after his family.
