Tax the Nords!

Since, according to Daron Acemoglu, James A Robinson and Thierry Verdier, they're freeloading on the Americans doing the heavy lifting (not to mention benefiting from our military spending);

...the main implication of our theoretical framework is that we cannot all be like the Nordics! Indeed it is not an equilibrium choice for the cut-throat leader, the US, to become cuddly. As a matter of fact, given the institutional choices of other countries, if the cut-throat leader were to switch to such cuddly capitalism, this would reduce the growth rate of the entire world economy, discouraging the adoption of the more egalitarian reward structure. In contrast, followers are still happy to choose an institutional system associated to a more egalitarian reward structure. Indeed, this choice, though making them poorer, does not permanently reduce their growth rates, thanks to the positive technological externalities created by the cut-throat technology leader. This line of reasoning suggests therefore that in an interconnected world, it may be precisely the more cut-throat American society, with its extant inequalities, that makes possible the existence of more cuddly Nordic societies.

Isn't that what the Labor Theory of Value requires?
