Large multinational corporations, often acting through their industry lobbies, exert a powerful influence on the formulation of domestic rules and on their application - but their influence on supranational institutional design is even larger because it faces practically no opposition there.

Social rules are susceptible to moral analysis. This is, again, relatively familiar in the domestic case, where we now condemn slavery as unjust. And when we affirm this judgment, we're not merely saying that all those people who owned slaves were unethical people; they shouldn't have done that. We do believe this, but that's only part of the point. We also believe that the fugitive slave laws were unjust.

Domestic and supranational regulatory capture leads to two things: on the one hand, to an inequality spiral where the rich get richer because they can influence rulemaking and rule application in their favor; on the other hand, it also leads to instability. This is so because the relatively few organizations capable of influencing supranational rulemaking through the lobbying of major governments have diverse interests. This will, in some cases, lead to compromises. But it will also lead to spheres of influence.

The fact that oppressive and corrupt regimes can borrow money in the name of the whole country means that the country's future generations will be weighed down by interest and repayment burdens, even if the money has been frittered away in some frivolous way, embezzled or used for weapons to suppress the country's population.

Whatever we, as prospective participants unaware of our specific features, would desire society to be like is what, morally speaking, we ought to institute.

The collective income of all these people - the bottom half - is less than three percent of global household income, and so there is a grotesque maldistribution of income and wealth.

Though people could, in principle, cross national borders to reach places where their work is more highly rewarded, they are in fact prevented from doing so. As a result, huge differences also persist in the price of labor, as you can see when you get a haircut in rural India or hire a driver or babysitter in Bolivia. You can easily buy such services at one-fiftieth the price you would pay in London, Hamburg or Manhattan.
