What are you talking about? Unions are a 19th century European (mostly British) invention. Sinclair is a 20th century US writer, 100 years before him there were already strikes all over the world requesting better working conditions.
Spartacus is crying on Hades' shoulder due to your insensitive remarks. Organized conflict between social strata has been happening for eight thousand years. It's not particularly British. Nor was the movement to abolish slavery. That's a French and Vatican invention.
