Can Buddhism help me escape the difficulties in my life? I am tired of the rat race, working a job I hate to buy things that I don't need.

I am tired of technology and the grasp it has on everybody in the western world.

Is there a feasible way, within Buddhist practice, for the average westerner to escape it all in exchange for a simple and pure life?
Of course. Realizing that you don't need things or that those things aren't going to make you happy is the beginning of awareness that the worldly world is not as great as you thought it was!

Fortunately, the Buddha laid the grounds for understanding exactly this sort of suffering and how to remedy it with the Four Noble Truths. 

No need to be like everyone else in your society/community. Change your lifestyle in any way you see fit to give you time to study, practice, and explore that which leads to true happiness. No need to live in a cave to do this either; unless you want to. But people can live incredibly simple lifestyles anywhere as long as they aren't trying to fit in with those around them. Best wishes in your journey to true happiness. :)
