A tremendous amount of things in the past were created by skilled artisans, workers, farmers etc.
And in those cases where people had to do difficult work and suffered, that was because there were no other ways of accomplishing that work.
It's not that there was some cabal of evil leaders making life hard for the masses, it's that in order to accomplish things like mining and large scale public works without machines, hard manual labor was necessary.
Of course we could have just not done any of this, but then we would still be hunter gatherers.
