Easy Rider
"[T]hier journey, and its eventual lack of fulfillment, comes to mirror ironically the unfulfilled desires proffered by the consumer/materialist culture they take flight from." I believe that the scenes that aptly embody Easy Rider's tag line ("A man went looking for America and couldn’t find it anywhere.") would be the scenes where the redneck townsfolk are featured and play a part. These people are the antithesis of some of the tenets of America (freedom for all people, specifically). America used to the be the place where people could escape oppression and bigotry when it was originally founded, and here are American citizens shunning, shaming, and even murdering their fellow citizens. These people are far removed from the America of the past and the America that Wyatt and Billy seem to be searching for.
It is evident that they fled LA because they were not satisfied with the America there, and set out and failed to find it. There was no more simplicity, friendliness, and freedom in civilized areas: the closest they found to these aspects were when they dined with the rancher and his family and while they were on their own on the road. To find what they were looking forward, they would have to be completely cut-off from "civilization".
