... then assuming that the field is no more labor intensive per dollar than the US economy as a whole (I think that's a safe assumption), and assuming that the wind turbines will deliver power with greater value than their installed cost, then the job creation overseas (China, y'all, wherever) is:
85%x60% = 51%
15%x60% + 40% + (>50%) = >99%
So not allowing the stimulus money to be spent on projects where the wind turbines are imported is killing off 2 American jobs for each one job overseas that is avoided. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
