if you have enough wealth for a corrupt second/third world government to care about you have other ways to deal with this problem

also, another aspect of "run away" is "from the city" where the government forces are concentrated and more likely to find you

out in the country, people don't tend to be so fond of the tax man, and the police tend to be more focused on securing their fellow citizens from crime

or at least, looking like they are
