In what way did the social organization of the industrialized soviet union come to resemble that of the west?

The correct answer is The division of urban society between workers and a managerial middle class

Although they claimed that all classes were abolished and all kinds of things like that, they actually weren't and there was a clear distinction in earnings and the lifestyle of those who were managers who formed some sort of a middle class and those who were regular workers who formed the working class or the lower class.
