Women's advocates insist employers everywhere pay women less than men for doing exactly the same work in the exact same occupations and careers.

Yet these advocates also seem to think employers' prime modus operandi is greed. Thus they no doubt believe employers would hire only illegal immigrants for their lower labor cost if they could get away with it (many do get away with it), or would move their business to a cheap-labor country to save money, or would replace old workers with young ones for the same reason. 

So why do these same advocates think employers would NOT hire only women if, as they say, employers DO get away with paying females at a lower rate than males for the same work?
