Cuba let 20% of the population leave in 2020-24 so that they would have fewer dissenters in the country who might overthrow the government. Thats a higher rate of population per year than the peak of the great Irish famine

if they don't let people leave to prevent total state collapse then they're starving their own people (by means of the american trade embargo); if they do let people leave, it's to tighten their stranglehold on the country.

Where does one go with one of the weakest passports in the world, no assets, no family connections, and probably only sporadically any skills capable of getting a work visa? I need to get on speed dial whatever immigration lawyer those people had.
