So the fundamental question is, "What did these people expect?" (and were thus disillusioned when they didn't get their expectation). Did they expect that they would be able to build large foreigner controlled businesses? Did they expect that their success would not be impeded by a desire on the part of political entities to craft a narrative? Did they expect to secure more wealth for themselves before they were shut down?
I am always surprised by people who think they can do what they do in their home country in any other country and get the same results. But it is particularly true of people in the US it seems. If you don't really internalize how the laws, politics, and policies of a country shape what is, and what is not possible, you are setting yourself up to be disappointed.
