United and American ought tell Springfield and Chicago and the RTA and all these parasites to get screwed, that they are moving their headquarters as rapidly as they can to Texas or somewhere that wants businesses to thrive. Then do it.
Why? Chicago has good infrastructure, that costs money. United is skirting their obligations through a (legal) loophole, which is certainly sketchy. Rather than suing United, they ought to just eliminate the loophole going forward.
