Increases in crime is what drives the need for additional prisons. In strong economies, as we have been experiencing, the rate of crime generally goes down. As the economy weakens and employment rates decline crime then begins to climb. Of course, the more crime----the more prison requirements----assuming 'the process' does it's job. If you believe we will continue to enjoy strong economic growth in the near/longer term, then don't invest in PZN. I believe history repeats and our economic cycle will, unfortunately, experience a downturn in the not too distant future. How long can we absorb personal 'bankruptcies' at the current record pace---in the best of times? Imagine what's ahead if things take a turn for the worst. I don't like sounding so negative but just trying to be realistic. PZN seems to have a very good future from what my crystal ball tells me--- It's a contrarian way to find value but I'm putting some money on it NOW.
