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
