Whoever tries to hold up the Keystone Pipeline as a way to create jobs in this country is lying to you. According to Cornell University's Global Labor Institute, "The project will create no more than 2,500-4,650 temporary direct construction jobs for two years, according to TransCanada’s own data supplied to the State Department." 200,000 jobs were created in December 2011 alone. So he total amount of jobs created over the projects entire lifetime would only amount to around 1/43 of the amount of jobs currently being created in the US in one month alone. And most of these are just temporary jobs, with the amount of permanent jobs created in the hundreds. By contrast, the census created over a hundred times as many temporary jobs as the Keystone Pipeline would.
So whoever is telling you that the Keystone XL Pipeline would any noticeable impact on job creation is lying to you, and it's time to tell them to stop.
