I don't believe there will be civil unrest but things are going to get progressively worse and people are going to get more and more desperate. So organised crime gangs are likely going to increase in power while "the government" looks the other way or does things that does not help, like restricting your freedom and privacy. Nevertheless the result is more and more inflation and eventually you will just be living within a single square mile. No car, no travel, just you and your fellow neighbours either screwing each other or getting screwed by gangs or maybe both.
