What are the main points in Fast Food Nation: The Dark Side of the All- American Meal?

It will be difficult, if not impossible, to offer a
complete summary here.  The main points that Schlosser brings out revolve around the
food preparation in "fast food" establishments, the desires to increase consumer
purchase and consumption of food, and how there is a subterranean force of malevolence
underneath the "fast food" establishment that has enshrined itself as a part of our
culture.  Schlosser discusses how the industry has colluded with other elements to
ensure that profit and the continued profit of the fast food industry is here to stay. 
This involves the shortchanging of farmers as well as consumers in the need to generate
profits on a gargantuan scale.  This drive for profits has created some undesirable side
effects in terms of health and social contexts, as evidenced in the analysis of Greeley,
Colorado, a town that helps to drive the meatpacking component of fast food industries. 
Both in food preparation, animal slaughter, and human cost, the need to deliver profit
is something that Schlosser makes life not worth living and food not worth
eating.
