What makes you believe an economic collapse would bring something better?
These injustices happen everywhere. The whole world is fucked up when you think about it. I'm not sure a collapse would bring something better.
Definitely scary. It may really happen to anyone. The "reason" might be totally banal, like somebody got interested in your wife...
Did you read the chicken man story I linked above? He ended up dead because some municipal officials wanted to build a "green area" on his property.
