Globalisation is undermining the basic stability of nation states. The globalisation of labor markets hollows out the middle class in developed nations and spurs the rise in incomes among the poor in developing nations. But the corporate class that benefits the most from the economies of scale of globalisation has no allegiance to any nation state anymore, labor is disposable and subject to arbitrage. So there is no incentive to pay for the physical and institutional infrastructure that nation states provide, corporations can just hop to the next developing nation willing to bid down the price of labor.

Global supply chains turn nations into specialized units in the chain so whole sectors of a nations economy are decimated in the interest of global efficiency but the result is that nations become less self-sufficient and more dependent on globally supplied commodities and services.

So nation states have less control over their economies, are less able to generate dependable revenues and less able to provide basic services to their citizens.  

But the externalities of doing business - pollution, infrastructure, social disruption and resource depletion - are only externalities within the economies of nation states subject to global arbitrage. In a globalized economy there are no externalities, only delayed costs. And now we are all beginning to pay for those costs.
