It seems safe to say that in the past technological change created mor
e jobs in total than it destroyed. That this was true in the past does
not mean it will be true in the future. As advanced industrial econom
ies struggle with jobless growth, tower-income countries will have to
create new jobs in very large numbers. With technology, in all its for
ms, reducing the direct labor content of production in almost all sect
ors, it is not clear that there will be enough work either the develop
ed or the developing countries. Any transition to sustainable developm
ent requires that most people in most places achieve levels of economi
c security they deem adequate. Thus, creating decent jobs by the hundr
eds of millions poses a fundamental bottleneck to sustainability. (C)
