Which best describes how economic growth has changed japanese society since the us occupation? only two economic classes have remained. wealth has been equally distributed throughout society. a sizeable middle class has developed. most of the population has amassed great wealth.

The answer to this should be: A sizable middle class has developed. 

With a middle class they can create a better governance; The Middle Class has a strong interest in promoting foresighted policies and making government work well because their economic fate is more closely tied to the quality of government than that of the wealthy.

Hope this helped :)
Have a great day
