Why is it "American's hunger to move"?

Is it a lack of identity (i.e. being a mixed bag of ancestry such as Germanic, Celtic, Anglo-Saxon) and the search to find one?

Is it something in the land pounded into the earth by the feet of it's nomadic natives long ago?

Is it the near constant expansion since the days of Lewis, Clark, Pike, and Hudson?

Could it be the cyclic disillusionment inevitable in the culture and economic cores of the country?

Is there just too ******* much space?

It would be easy to blame President Eisenhower for the whole thing by giving people a means of traveling the whole country so conveniently in the first place.

But I don't think that is it.

Who am I to know though? I'm not even pretending to have an answer.
