No draft as such - but poverty does the trick well enough, and at the same time it avoids antagonising people with power. Neat trick.
Last verse of Pick up a Gun by Ralph McTell, who joined the army at 15, but his parents scraped together the money to buy him out
:
Old soldiers never die, they only fade away,
But the young ones do not die, no they are cut down instead
And someone pulled the trigger,gave the order, held the sword,
and someone wrote the advert in the paper that they read.
Thy will be done,
But you won't get your hands on my son,
you can wait till kingdom come.
