Really, you need to actually go out and meet the world around you. It isn't all wine and roses I assure you, but it is better than living in a bubble, those burst, you know.

Just walk into an alley at night in Manhattan or Chicago or Boston or Los Angeles or (surprise!) San Franciso and you'll know... Seriously, read the newspapers of any more or less poor third world country and you will find many notes about people mugged and killed, stabbed or shot to death, to steal them some US$75 chinese MediaTek shitphone you can find in Amazon.

I'll give you some newspapers in Latin American cities that range from 6 to 25 million inhabitans:
