The Importance of Having a Local Nursery

Western political and military leaders seem to be doing a lot of hard talking about military capability these days, yet people and talent issues seem to be rather lower on their agenda than the excitement over technological 'silver bullets'. Poor recruiting and retention rates make planned force designs look increasingly untenable, something which no amount of technology is going to solve in the short to medium term. One might wonder, then, why militaries seem rather agnostic about  recruiting from only a small minority of the population when some simple changes could radically alter that dynamic. Is it a lack of will or just an ambivalence to the issues?
