The New Orleans Times-Picayune reports: 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.

Several homegrown private prison companies command a slice of the market. But in a uniquely Louisiana twist, most prison entrepreneurs are rural sheriffs, who hold tremendous sway in remote parishes like Madison, Avoyelles, East Carroll and Concordia. A good portion of Louisiana law enforcement is financed with dollars legally skimmed off the top of prison operations.

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.

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.
