There are two reasons. First, jobs in such places are generally less skilled.

This is a particular worry for the poor and underemployed in Africa and India, where industrialisation has stalled at low levels of income—a phenomenon dubbed “premature deindustrialisation” by Dani Rodrik of Harvard University.

Rich countries have more of the sorts of jobs that are harder for machines to replicate—those that require original ideas (creating advertising) , or complex social interactions (arguing a case in court) , or a blend of analysis and dexterity (open-heart surgery) .
