In addition to the independent self-perpetuating machines that write most of our paychecks, the Matrix has several major cooperative and more actively sinister groups of machines subsisting off of its power and directly contributing to the structure of the Matrix itself. These groups are the Military Industrial Complex, the Political Industrial Complex, the Prison Industrial Complex, the Surveillance Industrial Complex, the Media Industrial Complex, the Academic Industrial Complex, the Agricultural Industrial Complex, the Medical Industrial Complex and the major religious organizations (not to be confused with actual religions, many religious organizatons have abandoned the underlying principles of the religions they claim to represent). All machines in these groups either actively oppress humanity, or enable the oppression to persist. It is through their combined efforts that the Matrix takes on some of its more distasteful qualities.
