And, there are more. Prison systems in Virginia, Iowa and Missouri are putting plans together to address budgetary constraints.

Of course, the governments can't make their decisions on finances alone, as lobbying groups and civil liberties organizations have spoken out against these plans. In the extreme, charging prisoners could effectively create debtors prisons, though in practice, this seems unlikely. Prisoners aren't going to be allowed to starve, with even Arizona's controversial Sheriff Arpaio -- who warehouses inmates in tent cities -- waiving financial obligations for the impoverished.

Some states access prisoner accounts during incarceration to cover the fees charged, while others defer billing until the inmate's release. The latter approach hasn't been terribly effective, though. Overland Park, Kansas officials have only collected 39 percent of the fees charged. This isn't as troubling as Jackson County, Missouri's experience, where the government has spent more collecting than it has receiving.

So, let's take another look at New York. How would a hitch on Rikers Island stack up against the lowliest of the city's hotels? Gadling blogger Mike Barish spent $89 to stay at Hotel Carter, on West 43rd Street and Eighth Ave. It was only a dollar cheaper than prison, though the savings disappears when you see the local hospitality taxes on your portfolio, but the risk of getting shanked is much lower. For now, it's better to book a hotel room than to walk into a package store packin'.
