his book in many aspects is very powerful because he demolishes many stereotypes, myths and "magic bullets" about economics, which flourish even here on ET up to date.

His means to eradicate extreme poverty seem to me very reasonable. It is a scandal how less developed world contribute to this noble goal, especially US, France and Italy.

His means include strengthening and empowering UN institutions, especially IMF and WB on condition that they change their usual ways. This is ongoing process as we all see, because Western powers far too long monopolized decision taking in these vital institutions. Now after developing countries like BRIC agreed to hike their contributions to IMF and WB budget I hope they will have more say in decision making process.

Then, Mr Jeffrey Sachs is absolutely right when he speaks about urgent need of massive external financing of the first very difficult step on the ladder of development. When one particular country is desperately poor in the first place no matter how good governance will be it still will be very poor country after many decades. Many African countries unfortunately were caught in this poverty trap and without helping hand they will not raise themselves out of trap.  

The poorest countries have also slim chances to be useful for richer countries on geopolitical reasons, getting much needed grants, but this rule usually not applied incase of war and poverty ridden (often landlocked) African nations.
