I used an example that would have been applicable a hundred years ago, because I'm not sure what 'should be disappearing' jobs would be protected from what 'not yet here' innovation under such a misguided policy - I'm smart, but my future-telling abilities are rather limited. Perhaps a more timely observation would compare steel-mill jobs to internet jobs, tho that's still rather dated. Perhaps. But what in, and who should pay for it? Using my example above, the government would most likely pour lots of taxpayer money down holes like 'improved buggy-whips', 'improved buggies', and 'horse hybridization' rather than internal combustion engines, mass production, and other innovations that private industry brought forth at no or minimal cost to the taxpayer.
