• High crime rate which is the basis for the premise of that world is probably a result of high poverty
• State responds to it by profesionalizing "heros" which are just glorified cops
• Extreme glorification of "heros" in the media and propaganda
• "Heros" must form or work at private hero agancies so that means they are privatised
