Re: What cost per recruit?
Investing in people? What a preposterous idea. How would one pay back all of ones public school friends that have helped one get this far?
Instead, if the UK can continue to under invest in education and housing, offer a very modest increase in benefits to teenage single mothers, ensure a cheap supply of alcohol and offer "the Army" as a way of providing a career when the alternative appears to be prison and you not only save all those costs but maybe save a little more along the way.
Just have to be careful about keeping a balance between those in the Army and those wanting to start a civil war....
