The men who laid the tracks were low skilled workers who had ZERO experience when they were hired. Anyone could do that job.Building railroads doesn't require skilled craftsmen. It was all about hard labor.I'm definitely not denying that. They contributed to an economic boon, but they didn't build anything. That would require skilled training that slaves never received.Nobody claims they built all of America
But you can't claim that four million slaves in a ten million population in the south was not significant
The southern economy was built on cotton. Slaves planted it, maintained it, picked it, bundled it,transported it, ginned it
I wouldn't go that far
There were slave craftsmen and carpenters that did construction. Slaves built the railroads in the south. There were slave blacksmiths
The economic boom in the south was built on the backs of slave labor of which they received nothing
Building railroads took tons of skilled craftsman- blacksmiths, carpenters, bricklayers, tinsmiths- there is a whole logistics train that goes with building a railroad.
You needed people who could build bridges, build up the structures to support the construction, build the wheels for the wagons, build the wagons, build and repair the tools.
And? Even if that is true- I have already refuted your claim that building railroads doesn't require skilled craftsmen.
