More and more workers who had the idea their jobs were secure, and were used to comfortable incomes, suddenly get a layoff notice. Then they find it impossible to get another job in their field or at the same pay level. The unskilled and semi-skilled labor of great numbers of workers, especially minorities, is no longer needed due to automation and industry's flight to the third world. They become permanently excluded from the regular workforce with no hope for a decent standard of life. These economic pressures take a heavy toll on personal relations.

While identifying these causes of violence, the commentators are nevertheless at a loss to find a solution for it. It's not because no solution exists. Intellectually chained to the status quo, they are prohibited from acknowledging that the social breakdown they describe is the inevitable product of the competitive system and can only be reversed by building a new economic system. The liberal idea is that the social problems from a competitive market system can be solved without changing the economic system. The government, liberals say, can and should intervene not to eliminate the pursuit of profit, but regulate it and to aid the victims of its social destructiveness.
