Your environment was predictable, in that savings up enough would likely give you the option to move out. There are places where saving up enough money to leave your unpredictable environment unpredictably ends with you drowned in the Mediterranean, or in limbo short of your intended destination, or shipped back to where you spent so long trying to leave, in addition to the "success" case.
I guess it depends on the meaning of predictable? We couldn’t predict 1 usd = 5rub would turn into 1usd =25rub almost overnight. My parents had friends in business killed (sadly not predictably) so it was unpredictable when it would be their turn.
