Ten Keys To Latin America (Vintage Books)

What can a 60 year old book say to current US citizens ? The author points out that public health measure and malaria control led to an expanding population, especially in Mexico, In 1956 there was a population of 30,000,000 and by 2000 a population of 100,000,000 was antifipated. No wonder the US has experienced the immigration that has been coming from the end of the last century forward.
