The widespread assumption that big business and big government are fundamentally at odds, and that big business supports a free market, serves to maintain the ruling partnership in power. ... The establishment left disguises its government intervention on behalf of the rich as government intervention on behalf of the poor, while the right disguises its government intervention on behalf of the rich as an opposition to government intervention per se – and each side has an interest in maintaining the myth propagated by its nominal opponent. For those who are repelled by the realities of corporate capitalism are lured into becoming opponents of the free market and foot soldiers for the left wing of the ruling class, while those who are attracted by free-market ideals are lured into becoming defenders of corporate capitalism and foot soldiers for the right wing of the ruling class. Either way, the partnership as a whole has its power reinforced.
