Louisiana is #1 in the world when it comes to imprisoning people.

Louisiana is the world's prison capital. The state imprisons more of its people, per head, than any of its U.S. counterparts. First among Americans means first in the world. Louisiana's incarceration rate is nearly triple Iran's, seven times China's and 10 times Germany's.
The hidden engine behind the state's well-oiled prison machine is cold, hard cash. A majority of Louisiana inmates are housed in for-profit facilities, which must be supplied with a constant influx of human beings or a $182 million industry will go bankrupt.Meanwhile, inmates subsist in bare-bones conditions with few programs to give them a better shot at becoming productive citizens. Each inmate is worth $24.39 a day in state money, and sheriffs trade them like horses, unloading a few extras on a colleague who has openings. A prison system that leased its convicts as plantation labor in the 1800s has come full circle and is again a nexus for profit.In the past two decades, Louisiana's prison population has doubled, costing taxpayers billions while New Orleans continues to lead the nation in homicides. One in 86 adult Louisianians is doing time, nearly double the national average. Among black men from New Orleans, one in 14 is behind bars; one in seven is either in prison, on parole or on probation. Crime rates in Louisiana are relatively high, but that does not begin to explain the state's No. 1 ranking, year after year, in the percentage of residents it locks up.Despite locking up more people for longer periods than any other state, Louisiana has one of the highest rates of both violent and property crimes. Yet the state shows no signs of weaning itself off its prison dependence.
If the inmate count dips, sheriffs bleed money. Their constituents lose jobs. The prison lobby ensures this does not happen by thwarting nearly every reform that could result in fewer people behind bars."You have people who are so invested in maintaining the present system -- not just the sheriffs, but judges, prosecutors, other people who have links to it," said Burk Foster, a former professor at the University of Louisiana-Lafayette and an expert on Louisiana prisons. "They don't want to see the prison system get smaller or the number of people in custody reduced, even though the crime rate is down, because the good old boys are all linked together in the punishment network, which is good for them financially and politically."The lobbying muscle of the sheriffs, buttressed by a tough-on-crime electorate, keeps these harsh sentencing schemes firmly in place.
"Something has to be done -- it just has to be done -- about the long sentences," said Angola Warden Burl Cain. "Some people you can let out of here that won't hurt you and can be productive citizens, and we know the ones who can't."
