Orcs and other beings in LotR are evil because Morgoth infused the world with his essence and his ill will. At the end of the First Age, he was a shadow of his former self and was easily defeated by the other Valar. But since he basically turned Arda into his Ring, truly eliminating him would probably meant remaking Arda from scratch. Therefore, he was just cast out into the Void, and the Valar retreated to the few parts that were still intact. Of course, that's the official mythology, and the truth might be rather different. There is no inherent stigma against industry in itself in LotR. Many peoples (Noldor, Numenoreans, Dwarfes) engaged in industry, but it tends to further greed and hunger for power, which makes individuals and whole societies easier to manipulate and play off against each other.
