Ruling Canada: Corporate Cohesion and Democracy
Author: Jamie Brownle
The "economic elite" has long been thought to cooperate at a corporate level to impact state and national policies and programs at the expense of the Canadian citizenry. However, this work reveals the expanding reach of the elite and their current encroachment into the noncorporate arena as yet another opportunity to exert their formidable influence. Citing the increasingly unified and class-conscious aspects of the group, this text reveals the degree to which this minority continues to prosper, dominate, and threaten Canadian democracy through numerous unifying mechanisms: corporate director interlocks; concentrated economic ownership; ties to the mass media; and the many business-oriented think tanks, philanthropic foundations, and corporate policy organizations. Maintaining that these existing relations need not be considered inevitable, the author challenges concerned citizens to come together to disrupt the political and economic status quo.
