Some might question the quite accepted role the government has in directly creating jobs and investment [in this particular instance]. I come from the school that govt, per se, shouldn't have have any sort direct over lording or say so in the said suspicious creation of jobs, investments, etc. Government intervention tends to muck most everything - not always.....but a better chance that government requires a hand in every circle of endeavour.
What their purpose might be is to create overriding and balanced policies that encourage the markets to flourish naturally and grow accordingly without the false premise of govt interplay.
Of course, in this case [and many other similar instance the world over] the bottom line for such economic projections has little to do with the benefit of the commons, but more to do with the success of those elite classes.
