In my city, businesses are routinely courted with promises of special tax treatment. Ironically, it's nearly always for businesses that don't need the tax break. Target, for example, was offered a deal where if they built a warehouse here they wouldn't pay any city taxes for 20 years. I don't see how that's different from what happened in Ireland. Apple build facilities there and employed people, bringing in an industry that otherwise wouldn't have gone there. For that, Ireland lowered Apple's taxes. That happens all the time in the U.S.
