Marx:
Today’s wage-labourer is tomorrow’s independent peasant or artisan, working for himself. He vanishes from the labour market - but not into the workhouse.
Sakai:
A study of roughly 10,000 settlers who left Bristol from 1654-85 shows that less than 15% were proletarian
many English farmers and artisans couldn’t face the prospect of being forced down into the position of wage-labor.
Is it the difference of time periods? I just noticed now that the time period Sakai is talking would be a pretty early period of colonization, wouldn’t it? So it may be that by Marx’s time of writing (late 1860s-early 70s?) it was proletarians headed to America and had been in recent historical memory?
You’re right that workers in the domestic system at that time, the pre-cursor to the proletariat, would not have the means to settle the colonies unless a corporate sponsor really needed their specialties.
All ships were disease ridden then, they are still disease ridden today, look at cruise ship statistics. The deadliest route to California from the US was a boat to Panama, taking the train across the isthmus, then a boat to San Francisco, an expensive itinerary - because it was the fastest. Highest rates of death occurred in this route due to disease. It was the poor and cheap who took overland wagons (which still cost a lot).
