Who benefits?
The Communist Party of Cuba’s elite, and the revolutionary movements they sponsor in Latin America.
The drop in oil prices is hitting Venezuela harder than almost anywhere else, and they have been subsidizing the Cuban regime. The Cuban communist regime needed an emergency bailout to avoid collapsing like the Soviet Union.
Since Raul took over, they have been restructuring to be like China - about a dozen generals are taking ownership of the State industries, so they will be the billionaire oligarch politburo members after the Castros die.
There will be no human rights or democracy, and the regime will be resourced to spread dictatorship in Latin America, and operate their spy rings in the USA.
BINGO!
This will not ‘trickle down’ to the masses in Cuba. The regime will simply continue business as usual and enrich themselves and their friends.
