exists?

Explanation:

The statement above is the point from the speech that most validly supports Warren's  argument that wage discrimination against women currently  exists.

The statement actually reveals the report from Bloomberg that analyzed Census data and discovered that median earnings for women were lower than those of men. Data from Census Bureau from 2018 revealed that women of all  races earned 82 cents on the average for every $1 that men of all races earn.

This wage discrimination is known to be gender wage gap which refers to the difference in earnings that exist between women and men.
