This is what the Equal Rights Amendment (ERA) says:
"Section 1. Equality of rights under the law shall not be denied or abridged by the United States or by any state on account of sex."
"Section 2. The congress shall have the power to enforce, by appropriate legislator, the provisions of this article."
"Section 3. This amendment shall take effect two years after the date of ratification.
After more then a generation of significant advances for women, do we still need the ERA? The answer, YES! Legal sex discrimination is not yet a thing of the past.
The Constitution has zero tolerance for any form of sex discrimination, thus the reason we need the ERA are at one level it is symbolic, and at another level specific and practical.
1. The ERA is is needed to affirm constituionally that the bedrock principles of our democracy - "liberty and justice for all," "all men are created equal," "equal justice under law," "government of the people, by the people, and for the people," apply to men and women.
Alice paul introduced the ERA in 1923.
