The first part contradicts the rest. World isn't fair, life isn't fair. That means there's no universal law declaring that every city has problems or that everyone has to struggle. Some cities (and countries) have much fewer and smaller problems than others, and life can be much more, or much less, of a struggle; regardless of you (in)action(s).

It is in fact exactly what it should be - a search for better life until you are satisfied with what you have, whether you are escaping war-torn Syria and hoping to run a barbershop in Beirut, or escaping boredom-torn SF and hoping to run a hedge fund in NYC. Nobody owes you either, therefore you have to make if happen all by yourself.
