>>8201sorry i posted the wrong video, i forget which one it is so im probably butchering cockshotts point, but basically labour supply had a big impact on changes in the mode of production and relations of production
so for example the roman transition from slave economy into semifeudal economy was driven by a reduction in the supply of cheap slave labor as the reached its limits of imperial conquest
another example is that the supply of peasant labour would bottom out due to landlords increasing exploitation making it harder to support large families, creating competition between nobles over limited surplus that would lead to crises which killed or drove the peasants off the land
