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.

To improve global health, it's not enough just to have a really good new product and to obtain marketing approval. You still need to market the product and bring it to patients, follow up, create the infrastructure, and so on - the whole pipeline, the network. That's something that companies are extremely good at: organizing a whole pipeline in a cost-effective way.

It is for the poor people's sake, above all, that we urgently need more unity and better organization and need to concentrate our reform efforts in order to really to achieve reforms, one by one.

It seems far-fetched, even preposterous, to blame the global economic order for the persistence of severe poverty in countries that are ruled by obvious thugs and crooks.

I think one big improvement would be if we somehow made it cheaper and easier for developing countries to learn from the sad experience of some of the developed countries, and also from some of the positive experiences we have of building good transportation systems, like high-speed rail.

Ordinary people like you and me can achieve very little on their own. We need to build support. Even if you are a thought leader and have some good ideas on how to make the world better, and even if you write five or ten books - that won't have much effect unless you have people who are willing to support your ideas.

To make a proper moral appraisal of the prevalence of severe poverty today, we should focus not on comparisons with times past, when the global average income was much lower, but on a comparison with what would be possible in our time, given the current global average income and level of technological and administrative development.
