Criticism to this theory:
It simply supports privileged position of those people who already have power, prestige, and money. In fact people can be motivated by the satisfaction of doing a job well, etc.
It assumes from the first that simply because social stratification has existed in the past, it has to continue in the future. It excludes a possibility of change.
The theory imply that the garbage collector is less important than the advertising executives for the society. This idea is difficult to agree.
