Simple, keep asking that question and then actually do it... Whenever we encounter something we think is wrong with the world, we have a choice of trying to figure out a solution or just accept it (the third option, looking for someone to blame, is an utter waste of time and energy).

If in doubt, focus on improving yourself, your intelligence, knowledge, compassion and sense of humor.
