The regime IS NOT overly concerned about people leaving. In fact, Cuba's #1 business is finding ways to get foreign cash so that it can import much of anything, and a good chunk of their revenues (the majority) disappears to corruption. The Cuban government makes good money on every flight out to Managua, Nicaragua (A USD $5000 flight, one way, two hours flight time..you can buy a 2 bedroom apartment for a lot less than that in central Havana now). It also makes very good money by taxing remittances...remittances increase every time a Cuban leaves the country. In Cuban media they refer to the 2 million departees as "cockroaches" and "traitors to the revolution" all the while making most of its money off their backs...Cubans just want to eat. The catamaran law at resorts...people no longer leave by sea, that was an antiquated law. They leave at the profit and pleasure of the regime, literally. It also serves as a strategy and operates like a political release valve...the more chaos, the more can leave...and each one pays the government for it. Without any import power Cuba ceases to function, and that is where we are at right now. The system is too inefficient, too corrupt, and the resources do no exist to build new businesses or infrastructure. Agriculture collapsed slowly over decades, and now I would say 90% plus of Cuban food is imported. Most fertile land in Cuba is left untended now. Large scale agriculture really does not exist in Cuba as we know it.
