Labor costs are a problem, but Kraft sure didn't move to Canada for cheep labor. With taxes, labor cost is likely the same or even higher in Canada. It's sugar costs that forced them out. They can buy sugar there at half the cost as in the US and the only ones who benifit from that artifically high sugar cost are a handful of millionare sugar farmers and FL & LA, and the Congress critters they bribe to keep the corrupt quotas in place.
Once again it isn't the cost of sugar it's labor and all the costs associated with it, i.e., health insurance, pensions; liability insurance cost (tort reform needed), infrastructure cost involved with old plant sites. As far as Kraft is concerned I'm sure they got a sweetheart deal from the Province of Ontario.
