I assume you mean "gender equality" as opposed to "gender inequality."
I would argue that, in the United States, we are gradually getting closer to gender equality. We are still not there yet, but we are getting closer.
On the public level, it is no longer unthinkable that a woman might become president of the United States. Hillary Clinton came close and there are those who think Sarah Palin might become president soon. Many states (even conservative ones like South Carolina) have female governors.
On the personal level, women are going to college and working as much as men do. In my own family, my wife is the main breadwinner and I have been only a part-time worker since the birth of our first child because I stay home with the kids. This is something that wiould have been practically impossible in my parents' generation.
