Look at how much money CCA spends on lobbying and supporting candidates that are friendly to their business. It is vastly larger per dollar of revenue than Apple (or Walmart). So much so, that it's one of the things people talk about when taking about whether Hillary Clinton (for example) is influenced by the money coming from the prison industrial complex. Nobody is accusing Hillary of being bought by Apple. Though there are concerns about Walmart, due to Hillary's long history with that company, but not because of exorbitant expenditures on lobbying and legalized bribery.
One (of many) articles about how CCA spends money to get the results that suit its bottom line. http://thinkprogress.org/justice/2011/06/23/251363/cca-geogr...
It's downright evil, frankly.
