Should women be paid the same as men for the same job?

Should women be paid the same as men for doing the same job? I am a firm believer in equal pay and equal opportunity. I don't care if you're a man or woman, if you're doing the same job, you both should be paid the same.

But if you work for the Obama administration, as a woman, you are apt to be paid less than your counterpart who happens to be a man. I personally think this is unfair to women, I think that it speaks to his administration and I think all women and men should be upset about this. I must admit this can be said about jobs in the civilian sector also but I don't think it should be the case there let alone at the Whitehouse. If you are doing the same job as me, you should be paid the same as me. What do you women (and men) out here think about this unfair labor practice?
