My Idea to Save Public Money

In an age of austerity when many people have not had a real pay rise for 10 years and many people have had big pay cuts, here is my big idea to save money. Women in the UK are paid on average 18% less than men.
But Lo! There is one woman that is being paid at least as much as any man that has ever done the job that she is doing, and is by all accounts, not doing the job very well at all!
THERES MAY could takea 15.5% pay cut and be relatively no worse off than any woman in the UK vis a vis men.
COME ON THERSA! Lay down your purse and give us some of our money back!
