As a private for-profit prison employing what is effectively cheap slave labor, you have zero incentive to actually reform or to reduce the amount of people who become imprisoned or the amount of time they are imprisoned for. You are in fact financially incentivized to do the opposite; classic perverse incentive.
As someone else in here posted, The Corrections Corporation of America noted relaxation of drug enforcement efforts as a RISK FACTOR in their 2011 10-K filing:

"The demand for our facilities and services could be adversely affected by the relaxation of enforcement efforts, leniency in conviction or parole standards and sentencing practices or through the decriminalization of certain activities that are currently proscribed by criminal laws."
Does this not scream "conflict of interest not in the interest of the greater good" to you? It does to me.
For an example of what happens when you allow this on a larger scale, see North Korea. Not a country anyone should be taking after!
