When a person has seen only a single sociopolitical system, it is easy to just shrug and say "it just is this way.". It is often only after seeing the totally different systems active in other societies first-hand that it becomes brilliantly clear that not only are the wrongs back home unacceptable, but that the other society you have found also possesses its own share of injustices that the locals are indifferent to. It is not wrong to be enraged at the suffering and petty evil everywhere. It is simply uncommon and stressful to try to do something since a single individual's effort may seem like that of an ant.
