I have found professionals in Argentina to be competent, some extremely talented. The general population is literate. Some may have limited cultural knowledge but in my experience no less so than the USA population. It's true, however, that quality of state school education has declined which accounts for the growth of private schools. Compared to the rest of Latin America, Argentina ranks high. It is especially strong on the university level which is why so many students from other countries choose to study in Argentina.
