John Kay writes  somewhat optimistically under the seemingly callous headline "Only the Poor Can Make Poverty History":
The good news about extreme poverty is that more people have been
lifted out of it in the past 10 years than in any decade in world
history; that this is mainly the result of rapid economic growth in
China and India, which is in turn principally due to internal reform
not external action; that the real contributions of rich countries have
mainly been through trade and investment, not aid; and that world
leaders have played only a minor though constructive role in that
process. The lesson is that world poverty will be ended by the actions
of poor people themselves.
