I think this kind of subsidy is only slightly better than sports stadiums. They both are shades of the bad parts of capitalism.
If only all states could agree to not give preferential treatment via tax subsidies. It'd be nicer for companies to pick their location based on geography and work force along with tax reasons.
I don't really think you can call this a "bad part of capitalism". States competing in a market for the patronage of large factories/firms is quintessential capitalism. All states agreeing not to offer tax subsidies would be classic cartel behavior, and would encourage more labor moving overseas. Now if their is evidence of Foxconn giving the WI legislate kickbacks, then I agree, this kind of stuff would be pretty nasty.
