About the first part, Basically every Nation-State that is in on the game has a better pool to draw from.
About your last comment. have you actually tried to Enlist in the last few years? i have, well re-enlist anyway. No one was hiring, i tried them all even Coast Guard. What i got over and over, no one was getting out, they were shining the total numbers, and with the down economy, the recruiters were basically not needed.
