Earlier quoted context omitted.
I don't think the New World Order conspiracy theorists were particularly paranoid about closing corporate tax haven loopholes.
I thought their whole schtick was "one world government," which is precisely what colluding to destroy tax competition is, as is banning capital flight which results from abusive policy.
And please: capital flight being the results of abusive policy? Corporations and wealthy individuals will always try to avoid giving the fair share to the society that enabled their wealth in the first place: the case where wealth moves because of abusive policies is so marginal in the ocean of pure greed. Some countries are fiscal parasites and benefit from the theft of other societies, and this is how we deal with parasites. Should we just watch wealth evaporate away to offshore stashes, wealth that actually belongs to the people?
