If there really is a difference in negotiating ability between women and men, it would seem far more beneficial to teach women how to negotiate for a fair wage rather than abolish the entire thing altogether. In fact, teach all employees to quantify their abilities and how much value they will provide to their employer. Demonstrate that if companies are unwilling to pay them a fair wage, that they should not devalue their employment.
But the most recent steps toward banning negotiation will ultimately hurt all employees. When companies like Apple, Google, and other Silicon Valley companies agree not to hire employees from each other, and threaten to replace tech workers in the US with less-expensive H1B visas, we should question their true motives. This newest idea of "banning negotiation" is nothing more than another tactic used by a profit-maximizing entity to reduce costs.
