Can somebody help me yze this quote? What do you think it is saying?

"That's my Middle West...the thrilling returning trains of my youth, and the street lamps and sleigh bells in the frosty dark....I am part of that, a little solemn with the feel of those long winters, a little complacent from growing up in the Carraway house....I see now that this has been a story of the West, after all - Tom and Gatsby, Daisy and Jordan and I, were all Westerners, and perhaps we possessed some deficiency in common which made us subtly unadaptable to Eastern life." Chapter 9, pg. 177
