Big Government where it is thought that people in power can make policies that will increase the happiness of the whole society is a religion these days, even Muslims have been infected by this. When the Rasul was told that people were raising food prices in the market in Madina during a drought, he replied that he could not control the price all he would do was try to encourage the merchants through preaching to them to not do it. Today most of us would want the government to control the price. This is a problem, when government interfere in this way they create un-intended consequence which make the problems worse. Socialism fails because it adopts Central Planning and Social Engineering and does not want to leave people to govern themselves.
