Quote:Three decades after the war on crime began, the United States has developed a prison-industrial complex—a set of bureaucratic, political, and economic interests that encourage increased spending on imprisonment, regardless of the actual need. The prison-industrial complex is not a conspiracy, guiding the nation's criminal-justice policy behind closed doors. It is a confluence of special interests that has given prison construction in the United States a seemingly unstoppable momentum. It is composed of politicians, both liberal and conservative, who have used the fear of crime to gain votes; impoverished rural areas where prisons have become a cornerstone of economic development; private companies that regard the roughly $35 billion spent each year on corrections not as a burden on American taxpayers but as a lucrative market; and government officials whose fiefdoms have expanded along with the inmate population. Since 1991 the rate of violent crime in the United States has fallen by about 20 percent, while the number of people in prison or jail has risen by 50 percent.
