From a psychological point of view, when people go under pressure in life, be it economically or otherwise, they seek support from the people closest to them, usually religious or ethnic groups. They also start blaming other groups who have more control over the national resources. If the gap of power is wide, this will eventually create deep divisions in the nation. The divisions can take on new forms of conflict such as class warfare, ethnic, religious, political unrest and sometime civil war. The only effective protection against national divisions is an open socioeconomic system with a large and growing middle class
