There is a great documentary called “The Century of the Self”, which is about the rise of consumerism in lockstep with politics in the United States.

The initial primary focus is Edward Bernays, nephew of Sigmund Freud, who is known as the father of public relations. He was incredibly influential during his time, having been a key advisor on most federal administrations from the 20s to the 70s. On the corporate side, early big wins were getting women to smoke at the dawn of the Great Depression, and changing the 'American breakfast' to bacon and eggs.

A core thesis of his is freedom in a large democratic state is a bit of an illusion… it needs to be controlled by consumerist impulses, or in other words, indirectly by corporations. Otherwise the all-encompassing hand of totalitarianism is needed. Without one of these mediating factors, the masses become unruly and descend into anarchy and chaos.

His late 20s book "Propaganda" is an interesting insight into his early, free from public scorn, view on the matter. It seems overwhelmingly cynical and puppet-masterish, if you will, and he somewhat stepped back from it after finding out how much it had influenced Goebbels. Still, I think it holds strongly as a guidebook for how the US evolved to present day.

In addition to Century of the Self, Adam Curtis has tons of other good stuff, too, and it's freely available:
