What comment does updike-through sammy-make on supermarket society?

Updike criticizes the consumer "supermarket" society and takes a cynical stance towards it as he sees all the consumers as sheep which are needed to conform to the "establishments" rule. He is against the objectification of the people and supports individualism but the powers that be want people to to follow their rules. The costumers in the supermarket are not independent, do not think for themselves.
