An eye for an eye leaves everyone blind. I am consistent across the board when I say I don't believe in violence, regardless of class, race, etc. Just because the rich are being violent to the poor doesn't mean an effective response is to be violent back; that's how you get your message smeared by media, and how you get the public to hate you. Take a page out of Ghandi's or MLK's book.

Violence will actively make things worse for the cause.

Also the rich aren't going to just stop exploiting people because they face death threats. Those people are very well protected by the government and by their well-paid, private security force. The only way to change things is to take control of the government. The how is difficult, since every part of the government is working for the rich, but that doesn't make it impossible. I hope it doesn't have to take a literal revolution to do so.
