The judging of an individual on the basis of the average characteristics of the group to which the individual belongs rather than the individual's characteristics is:
a. statistical discrimination
b. reverse discrimination
c. human capital discrimination
d. wage discrimination

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
