A former coworker came to the USA from Chile with a degree in Molecular Biology but couldn't find work in that field because of his language barrier. Instead he got a shitty job and build a small export company that sold used appliances and other goods from the USA to Chile. A big chunk were things like air conditioners, refrigerators, and washing machines. Even though Chile is a 50Hz 220V country 60Hz stuff will run off a transformer though sub-optimally which for most people is better than nothing. BUT he also found a more lucrative path by selling gun parts (mostly ammo parts like shell casings) hidden within said appliances. So there is an international market for this kind of stuff.
