How Does Credentialism Reproduce Inequality

How does credentialism reproduce inequality?

A) It discourages women to start college in order to meet and marry men who are college students without completing their own degrees.
B) It encourages people to earn only the college credits seen as valuable by employers seeking a specific skill set rather than devoting themselves to the study of topics that might not be as clearly related to a job.
C) It keeps wages low in employment sectors dominated by women, such as teaching, and high in those dominated men, such as computer technology.
D) As less wealthy people finally achieve a college education, those who are more wealthy are earning graduate degrees, which are now required by jobs that previously required lower levels of education.
