Not everybody's hurting under the Bush economy: Corrections Corporation of America, the largest private prison firm in the country, said severe overcrowding in the United States federal prison system is likely to help fatten the bottom line of corporate prison operators. Federal prisons are running at more than 130 percent of capacity, the company told investors. The majority of people incarcerated are male and between the ages of 18 and 24. With the overall population of this demographic increasing, the company assumes more people will be thrown into prison, also helping business. . . The company said the Bush administration's post-9/11 immigration policy of mass roundups and increased police presence in urban areas over the last four years has led to higher incarceration rates.
