I think you need to look at more historical precedent. And the fact that our culture considers 13 year-olds children and ancient cultures considered them adults.
Jossi came to the states in 1857 from Switzerland with his parents at the age of 12. The family settled first in upstate New York, but two years later young Jossi was running a small Limburger factory in the town of Richwood, in southwest Wisconsin.
A 14 year old managing a factory was probably somewhat remarkable. A 14 year old in the US working certainly wasn't.
