Violence and state failure are the most responsible factor for social and economic complications in most countries for four main reasons: Violence can lead to long-term social development expenditure, the consequences and cost of violence has immediate consequences on the economy, national economies become virtually powerless and can no longer function, and finally peace is important for social and economic development. Many of the world's poorest countries are troubled by war, political discord (other forms of state failure), and criminal violence. Violence and state failure are responsible for the unconstructive and detrimental impact on social and economic development in the South. Violence, political and criminal, can result in long-term social development costs in developing countries. Political violence affects social development in several ways. For example, in states experiencing intrastate conflict, infant and maternal morality rates are significantly higher, and their water infrastructure is even worse. Poor water quality affects social development. More than half of all diseases in developing countries are caused by poor water and sanitation conditions. Economically, water scarcity also applies to developing countries. They do not have the financial resources and human capacity to invest in water supply. It is a never-ending vicious cycle that begins with violence. On the other side of the spectrum, the effects of war violence in recent years, even decades after the war ended, are due to demolished health centers, war-torn citizens, and immense spread of communicable diseases. The spread of diseases affects economic development because it puts people out of work, fills middle of paper ......re and responsible if we want to have a chance of surviving the challenges" and "if we manage to overcome these difficulties to achieve peace, then the global economy will reach its maximum efficiency". For countries to grow socially, economically and politically, peace and prosperity must prevail. Violence and state failure are the reason for which countries cannot grow and develop. Peace is necessary. Violence and state failure are clearly holding back this area. In short, the adverse effects of political/criminal violence and state failure. The state on economic and social development slows progress considerably. As a result, states are weak and unable to provide support and security. They have neither the authority nor the influence to guarantee their citizens education and. high quality health care. Violence took over and accentuated the failure of the State.
