Why do economists work with facts rather than values?

In general, people choose to work with facts over values because morality is subjective. There is no such thing as objective morality because each person is their own unique blend or genes and experiences. No two people have led the exact same life. Facts cannot be argued with. They simply are. A fact is objective, and to reject a proven fact is simply not plausible. Values are subjective always.

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.
