When you ask a question like this it would really help if you could tell us what "this" is. I can't be sure of giving a good answer as this question is right now.
People usually say that the counterculture was a response to the culture of conformity that dominated the US during the 1950s. Historians usually say that this culture came around because Amrican adults were so concerned with getting on with their lives now that life was normal. They had lived through the Depression and the War and now they wanted to get ahead. They wanted to make money and have material goods.
Historians also say the conformity came about because of the rise of big companies (so workers needed to fit in to a corporate culture) and because of the McCarthy Era (people didn't want to seem different.
I hope that's what you were asking about.
