If one goes to usaspending.gov one can find out how much big government depends on big businesses for its intrusion. All agencies of government use contracts with private companies including big bussinesses including , Microsoft,  AT&T, EQUIFAX, NBC, Times Warner, Goldman Sachs, United Healthcare  to provide it with the high tech, telecommunications,  credit checking ,brocasting, etc. expertise and serves it needs to regulate, distribute funds, provide services, train its employees on how to do their work. Part of what the IRS and state and local tax collectors  takes from them in taxes comes back to them in contracts and in this sense big businesses "run" government at all levels.
