but it's certainly a "black" money thing.
I'm not sure that's always true. I think back to the 1980s when I had a Columbian friend. They were dairy farmers... but the largest dairy farmers in the country and the grandfather had been president of the country. They maintained an apartment in NYC and perhaps others. I was young and don't know details, but I think they were trying to offshore assets because they had seen a lot of countries in the region attempt to nationalize assets or have outright revolutions.
So, imagine you were a completely legit business person with a thriving business in Venezuela a decade (or more) ago. Black money or no, you would be trying to offshore assets before everything you had vaporized.
