Pastoral describes people who raise grazing animals, generally sheep or cattle, both species introduced by European explorers and colonizers (as were horses). Prior to Columbus no species of domesticated cattle or sheep existed in the New World, thus no "pastoral state." Describing the world Columbus and those who followed him discovered (for Europeans at least) as a "pastoral state of tribal people" shows a poor understanding of pre-Columbian history in the New World.
Early European explorers and conquerors described finding large-scale farming, cities, extensive trade networks, empires, warfare, and of course slavery. Archaeology and the remaining records of those people confirm European accounts.
We can condemn Columbus for many things, but neither he nor the Europeans who followed introduced violence and slavery to the New World. They did introduce novel pathogens which led to large-scale, if somewhat accidental genocide (prior to a germ theory of disease).
Large-scale industrialized slavery as introduced by Europeans was a new thing, though, outside of perhaps the Aztecs (if you look at the whole mass sacrifices thing as an 'industry').
Large-scale slavery existed prior to the European colonizers. Look at the history of Rome, Greece, Egypt, China, India. Ancient Rome and Greece had fully slave-based economies, more or less so depending on when and where you look. Over time the process got more efficient in economic terms, "industrialized" as you call it, but slavery existed almost everywhere, in many forms, as far back as we have records, and of course still goes on.
