I'm confused. The article was about the United States, which has an enormous regulatory apparatus. You're saying that's irrelevant to multi-national corporations that operate here?
Though, USA is an exception, achived arguably due to history of low market intervention. I would not say that the MNC does not care but achieving global monopoly in heavely regulated industry is very hard. Case in point, in banking industry (the most regulated sector), there is no private (or even public) global monopoly.
