Keep in mind that the last thing the locals want/need are expats who fled in the 60s coming back to rule them. Sure the help will be valued, but there is still some mistrust/animosity between the two groups. The people who fled look down upon those who stayed and those who stayed few betrayed by those who left.
im doing a bad job in explaining this, just know it’s all very complicated.
cuba, unlike most 3rd world countries has one major thing going for it. The population is HIGHLY educated with engineers, doctors, etc. they can do a lot of this own their own. Just need resources and freedom.
My greatest fear is that multinationals just come in and buy everything up from state actors / oligarchs and the locals are left out.
Last thing we need is a wrecking ball to come out and old cities go down for modern holiday inns and Disney world.
It’s a both very exciting and worrying time.
