It's not exactly a comprehensive interview, but I stumbled upon it, and having never heard Carlin speak specifically to this....
"...consenus reality is often intentionally misleading."http://www.youtube.com/watch?v=pow5_UYKaJ8Another Carlin quote re conspiracy:
"And people say, Oh, your conspiracy thing. Listen, don't be making fun of the word "conspiracy". It has meaning. Powerful people have convergent interests. They don't always need a meeting to decide on something. They inhabit the same clubs. They sit on the same boards. They have all this common ownership and they are very few in number. They control everything, and they do whatever they want.
two-party system keeps the people at bay. They give them microwaves, fanny packs, sneakers with lights in the heels, dustbusters, to keep them distracted, keep them just calm enough that they're not going to try something."
