Troubled Society

I saw the horrible news from TV last night. An unemployed man randomly chose landlords from advertisement of internet, then pretended that he wanted to rent a house and murdered the landlord and tried to kill his wife and son as well. What's wrong with our society? It's really sick in this world. When he was caught by police, I was shocked that the reason why he murdered the victims is because he lost his job for a while and he had bad experience to be defrauded over million dollars; therefore, he have to kill somebody to extend his angry to relsease his pressure.
I think that government have to expedite their policy of economy, try to figure out the efficiency policy to save people, or more and more unemployed person will lose their patience and make more and more troubles in our society.
