Un pobre guey writes: "Ah yes, the old "bad jobs are replaced by really good jobs" argument: FTA: "Government officials and industry executives argue that even if factories are automated, they still are a valuable source of jobs. If the United States does not compete for advanced manufacturing in industries like consumer electronics, it could lose product engineering and design as well. Moreover, robotics executives argue that even though blue-collar jobs will be lost, more efficient manufacturing will create skilled jobs in designing, operating and servicing the assembly lines, as well as significant numbers of other kinds of jobs in the communities where factories are." Is it true, or are we desperately pretending that this will all turn out fine, as it sort of did after the Industrial Revolution? What is the net change in number of jobs? Will displaced workers find replacement jobs?"
