i agree with your point about "service-related" jobs, but aren't those jobs necessary?
if you had more people "mining, growing & making", would that make those other "service-related" jobs unnecessary?
would you really want have a reduced military in order to provide labor for those "mining, growing & making" jobs?
we live in a more dangerous world than ever and i, personally, want this country to remain "Policemen of the World. Protector of Human Rights (when we think that is a good excuse and useful to our interests)! The calvary riding to the rescue of western civilization!"
