Freda - You're absolutely right.

When the Chinese came to N. America, they came without their families.

Iranian boys become soldiers at fourteen. Thats a pretty good reason for sending them elsewhere.

During the dust bowl, my grandfather farmed out his brood to relatives and headed to the west coast looking for work.

When men are separated from their families and seek work elsewhere, the money they earn is often sent back home to feed the women and children.

So David, exactly who are you referring to? Please be specific.
