I find interesting that you assume that disparity within nations is caused by differences in intelligence. While this is true (i.e.: differences in intelligence make a difference, sorry for the joke) there are many, many, other causes for differences: geographics (easy), social (not all the countries are permeable to social status changes) and so on... I feel this "all is caused by the intelligence" a bit ingenuous. But may be it is only my european culture speaking...

You misread his statement: > The overall result would be to flatten the income disparity about nations. (But it would have no effect on the disparity within nations, since that is caused by differences in intelligence, and that won't change.)

He's saying that local effects of a nation would quickly be brought up to par, whereas the distribution in nations wouldn't likely change.

I think the misreading was you misreading gtufano.He disputed the unsupported statement that income differences within a nation are mainly because of intelligence differences
