argued that no society has ever been totally unstratified or totally classless for the simple reason that there is always a necessary degree of specialization within a society.

The conflict theory criticizes the stratification of society because in this process some people get advantages of stratification and others get disadvantages.

Explanation:

Conflicts theory describes that stratification only beneficial for some people in society. This process is not helpful for all society. For example, conflicts occur when it argued that a basketball player gets millions of dollars a year in the contract whereas a school teacher gets only lonesome salary in a year. This is the stratification conflicts that perpetuate and create conflicts and inequality in society.

The conflicts theorist just want to spread awareness about the inequalities about the societies. Stratification plays a role in people's relationship to production. People are separated by a thin line in which either they work as an employee or be the owner of the company.

Thus here society could not be always Unstratified or classless for very simple reasons.
