I met someone who said that he looks for countries with currency problems so he can go in there and start businesses for very cheap. He did that in Lebanon and turkey when they had hyperinflation. He also said that during difficult times, the government will subsidize you to keep you open if you sell things people need like bread. He’s very wealthy now. 

 Yea I've heard of people doing things like that as well. Some call it disaster capitalism, meant as an insult usually, but it is a fitting term IMO and I see no issue with it. Taking a huge risk doing so, so if it works, good for them. They deserve it
