Purchasing power parities are not a reasonable method for comparing households across countries or currencies. The reason for this is simply that PPPs are sensitive to the prices of all the commodities, goods and services, that households are consuming worldwide, with each commodity weighted in the calculations according to its share in international household consumption expenditure.

Feudalism is an economic system where a few people own all the land and the others have no option but to be serfs on such a feudal estate. We now condemn feudalism. We condemn not merely the feudal lords but we condemn the whole structure of rules that sustained feudalism. I am asking people to think similarly about the world economy.

The extremely low respect Congress enjoys among the population indicates that the citizens understand broadly what's going on. But the lack of a realistic political reform path leads to apathy and the kind of mindless frustration that manifests itself in the Tea Party-style hatred of any and all government.

I think that many citizens understand how our system works, or rather, fails to work, for structural reasons. But who has the capacity and the incentives to bring change? The banks and other corporations love the system because it allows them to buy legislation that serves their own interests even at the expense of the vast majority of citizens. Incumbent politicians love the system because it allows them to raise millions of dollars toward defending their seats.

Because present procedures by design favor the affluent, the poor are being increasingly marginalized. And because the poor are so marginalized, they can exert little influence on institutional design decisions. We need to break out of this vicious spiral and create momentum in the opposite direction.

Critical journalism has gone out of fashion, or rather, it has been bought out. And so, we have much less of it than we did during the Vietnam era, where there was very critical reporting on the Vietnam War and a lot of disagreement among the media. Now you find that the media are much more homogenous, converging because they all must cater to the same community of advertisers. It's sad to see.

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.
