As a woman who entered the largely male economics profession some years ago, I am aware of the barriers women once faced in corporate America. Despondent at the lack of response to my resume, I even accepted a job as a flight attendant before finally landing a position at a think tank. But do women entering the work force today face the same obstacles their mothers did? I don't think so: More and more, regardless of gender, success depends on hard work, ambition, and adding value to the bottom line.
