Because it disrupts the competitive market
How doe s factory " disrupt the competitive market" in a market where most factories are winding down or closing? Where much factory and construction labor sits idle?
increasing costs for every other party
Are you writing this out of a fifty year old textbook or something? Give a concrete example of people who's costs increase when an Apple assembly factory is built in the U.S. Are you saying you are worried iPhone or Mac purchasers are going to have to pay a bit more?
It disrupts the revenue of better managed companies that are not reliant on tax breaks
SLAP. Back to reality, this is a FACTORY. It's not building anything that "better managed companies" are selling because there is no U.S. competition for Apple at this point... are you worried abut the "better managed company" Samsung???
An Apple factory would mean no less in taxes being paid by other companies and would mean more government revenue from Apple, along with many, many more jobs (some permanent). You have to be eight shades of crazy to look at that and not be pleased.
