What's Up With Women's Pants Sizes?

I have a question...why is it that when we buy a man pants, the pants have two sizes...the waist and the length, but when we buy women's pants, we find no such ease of purchase!

We can buy petit, average and tall to be sure, but why aren't pants offered to us via the inseams like they are for men? I mean for men you can get pants of lengths 28, 29, 30, 31, 32, etc. Why must we be bound to have pants of the wrong lengths so that we have to hem them to get them to fit?

Women, unite! Complain! Make your voice heard! We deserve to be able to shop just as easily as men do for proper fitting pants!
