That rarely works out. When a country collapses the ensuing is chaos going to be a very rough time. Recent examples include the collapse of the Soviet Union. The 90s were really bad for people there. A lot of them moved here to the US to escape that and try to find a better life. I worked with some of them. And now what do they have in Russia? A dictatorship that's not any better than what they had in Soviet times - certainly worse than what they had under Gorbachev.
People who assume that something better will rise out of the ashes of collapse, but that rarely happens. Better to try to work to make the system you have better even if in small ways.
